section 4 preflight preparations and launch

SECTION 4PREFLIGHT PREPARATIONS AND LAUNCH4-1All Sippican ZEEMET series Mark II MICROSONDES require preflightpreparations. These preparations include unpacking the radiosonde, preparingand connecting the battery, preparing the sensors and antenna, entering flightinformation into Win9000, and initializing the W-9000 system and the radiosonde(Mark II GPS MICROSONDES only). In addition, the balloon must be prepared and theradiosonde attached to it. After the preflight preparations are complete, the radiosonde canbe released, and its release is detected automatically by Win9000.The data from a radiosonde in flight can be received from as many W-9000Meteorological Processing Systems as are connected to the system computer, and addedand configured in Win9000. Win9000 can process, display and store the data receivedfrom all the systems simultaneously, and independently generate coded messages for each.Generally, the systems must all use the same in-flight radiosonde type; however, the datafrom as many as two different in-flight radiosonde types, which are tuned to differentfrequencies within the 400–406 MHz band, can be received from separate systems that usethe corresponding radiosonde.Separately, for each of the available radiosonde types, this section describes how toprepare and launch the radiosonde and save the received data. Before preparing aradiosonde for flight, however, you must activate each W-9000 Meteorological ProcessingSystem and start Win9000.To activate the W-9000 Meteorological Processing Systems and start Win9000:1. Apply power to the ZEEMET rack by switching on the OFF/ON switch on theAntenna Module or Power Module. Repeat for every ZEEMET rack that will bereceiving data from an in-flight radiosonde.2. Switch on the system computer and the monitor.3. Start Win9000. (See “Starting Win9000” on page 2-18.)4. After the Win9000 Main window opens, click the system icon for the system, or thesystem name, in the Flight Window Navigation pane, and then verify that theindicator in the Flight Controller Status window is a green check mark. Perform thissame check for every system that will be receiving data from an in-flight radiosonde.NOTE If the indicator in a Flight Controller Status window is a red X mark,choose System Configuration from the File menu, and then verify that the systemhas been added and enabled in the Win9000 System Configuration dialog box.Win9000 cannot acquire data from the W-9000 Meteorological Processing System if theindicator is a red X mark.Win9000 Processing and Display Software

Provides two separate displaymodes, Normal and Spectrum. In Normal mode you can have Win9000 automaticallysearch for and track the radiosonde’s signal, or you can manually tune the 403 Receiver inthe ZEEMET rack to the radiosonde’s transmit frequency. In Spectrum mode Win9000displays the relative signal strength of a band of received frequencies.The Tuner buttonenables or disablesmanual tuning ofthe receiver. TheTune button tunesthe receiver to theselected frequency.The Spec button switches theRadiosonde Frequency/SignalStrength display between theNormal and Spectrum modes. TheSearch button switches the searchfunction on or off. The AFC buttonswitches the Automatic FrequencyControl on or off.The Normal mode displays the relativesignal strength and the frequency of theradiosonde transmit signal beingreceived by the 403 Receiver. Thesignal strength and frequency aredisplayed in a graph as a vertical bluebar. The signal strength is indicated bythe height of the bar; the frequency, bythe position of the bar along thehorizontal axis of the graph. The SignalStrength and Receiver Frequencydisplays also indicate the relative signalstrength, from 0 to 255, and the precisefrequency in MHz. The frequency of theradiosonde transmit signal should residewithin the 400–406 MHz band, which isindicated by a bar on the horizontal axisof the graph.A bar indicates the frequencyband (400–406 MHz) withinwhich the radiosonde shouldbe transmitting.The height of the bluevertical bar indicates therelative signal strength ofthe signal transmitted bythe radiosonde.

The display background turns from grayto light blue indicating that the tune function is enabled. Then drag the slider at the bottomof the display in the direction of the desired receive frequency. A gray bar appears in thedisplay and moves with the slider indicating the new frequency while the TuningFrequency display continuously displays the new frequency. The position of the blue barand the frequency displayed by the Receiver Frequency display remain fixed, indicatingthat you have not yet actually changed the receiver frequency. Position the gray bar at theprecise frequency as displayed by the Tuning Frequency display, and then click the Tunebutton. The blue bar snaps to where the gray bar is and the receiver is tuned to the newfrequency. To disable the tune function, click the Tuner button again. The displaybackground turns back to gray. If the search function is on, Win9000 will continue tosearch for and track the radiosonde’s transmit frequency; if the search function is disabled,the receiver locks to the tuned frequency.The Spectrum mode provides a real-time spectrum analysis display of the relative signalstrengths being received by the 403 Receiver. The signal strengths are displayed in a graphover a frequency band of 395–410 MHz in increments of 288 Hz. The relative signalstrength at each frequency increment is indicated by the height of a vertical bar. Theposition of the bar along the horizontal axis indicates its frequency. When the radiosondeis transmitting, its signal should appear within the 400–406 MHz band, which is indicatedby a bar on the horizontal axis of the graph. The radiosonde transmit signal should be thestrongest of all the signals, and therefore be indicated by the tallest bar.To display the Radiosonde Frequency/Signal Strength display in Spectrum mode when itis in Normal mode, click the Spec button. The Spectrum display can be used to identifythe transmit frequencies of other sources that might interfere with the radiosonde’stransmitting signal, enabling you to determine the optimum transmit frequency of theradiosonde within the 400–406 MHz band.Instantaneous Elevation Angledisplay.

Scaling a Graph 6-116.2 Scaling a GraphYou can scale the graph in a Graphical display in the following ways:• Default• Automatic• Maximum• Manually6.2.1 Selecting Which Profiles on a Graph to ScaleIf more than one profile is displayed on a graph, you can select which profile to scale oryou can scale all the profiles at once. The default selection is all the profiles. To select anindividual profile to scale, right-click anywhere in the graph, select Scaling Mode from thepop-up menu, and then choose the profile. A bullet is shown next to the current choice. Toselect all the profiles, choose Scale All.6.2.2 Scaling a Graph Using Default ScalingDefault scaling adjusts the minimum and maximum values of the horizontal and verticalaxis of a graph for each profile to a default scale selected by Win9000. These values areinitially assigned by Win9000 when starting a flight or opening a flight data file. If youchange the graph scaling for one or more profiles, you can reset the scaling of all theprofiles to their default values. To use the default scaling to scale a graph, right-clickanywhere in the graph and choose Default Scaling from the pop-up menu.6.2.3 Scaling a Graph AutomaticallyAutomatically scaling a graph adjusts the minimum and maximum values of the horizontaland vertical axis of the graph for each profile such that all the profiles always fit exactlywithin the graph. To automatically scale a graph, right-click anywhere in the graph andchoose Automatic Scaling from the pop-up menu.To have Win9000 automatically scale the graph continuously throughout a flight,right-click anywhere in the graph, select Properties from the pop-up menu, and then selectthe Profiles tab of the Graph Generator Configuration dialog box. One at a time select theprofiles for which you want to continuously scale the graph, and then select theAutomatically scale axis during a flight check box in the Options area. When all of theselected profiles have been configured in this manner, click OK. Win9000 willautomatically scale the graph for each profile every minute.Win9000 Processing and Display Software

6-12 SECTION 6 Working with the Graphical Displays6.2.4 Scaling a Graph Using Maximum ScalingMaximum scaling adjusts the minimum and maximum values of the horizontal andvertical axis of a graph for each profile to the absolute minimum and maximum values forthe data type being displayed. These values far exceed the practical and expected valuesfor the data, enabling compression of the profiles within the graph. Using maximumscaling helps to identify extraneous data that might lie outside of the expected limits. It isalso useful when generating difference profiles where negative values of the data canoccur and would otherwise not be displayed. To use maximum scaling, right-clickanywhere in the graph and choose Maximum Scaling from the pop-up menu.6.2.5 Scaling a Graph ManuallyYou can manually adjust the minimum and maximum values of the horizontal and verticalaxis of the graph for any one or more of the profiles. To manually scale a profile,right-click anywhere in the graph, select Properties from the pop-up menu, and then selectthe Profiles tab of the Graph Generator Configuration dialog box. One at a time select theprofiles for which you want to manually scale the graph, and then enter the minimum andmaximum values in the Minimum and Maximum text boxes in the units shown in theHorizontal Axis and Vertical Axis areas.NOTE Scaling a graph using default, automatic or maximum scaling removesany manual settings.6.3 Zooming In on a GraphYou can zoom in on one or more profiles on the graph in a Graphical display. To zoom inon the graph, click and drag your mouse pointer to draw a box around the segment of theprofile you want to zoom in on as shown in Figure 6-5. For more than one profile, drawthe box to encompass all of them. Release the mouse button. The selected segment orsegments expand to fill the graph and the scales of the horizontal and vertical axis adjustautomatically as shown in Figure 6-6. You can repeat to zoom in further.NOTE To zoom out of a graph, scale the graph as described in “Scaling aGraph” on page 6-11.Operator’s ManualP/N 9017-205, Rev. C

All segments of all the profiles marked as bad will reappear.6.5 Generating and Displaying Significant LevelsYou can have Win9000 automatically and periodically generate and display significantlevels for the temperature, humidity, wind speed, and wind direction profiles on the graphin a Graphical display. Or you can manually select when to have Win9000 generate thesignificant levels. The profiles must have been added as described in “Adding andRemoving Profiles and Entering Their Settings” on page 6-4. In addition, the DisplaySignificant Levels check box on the Profiles tab for the Graphical display must beselected for one or more of these profiles. The significant levels are used by Win9000 togenerate the WMO and military coded messages.The significant levels can be generated and displayed during a flight, after a flight, or froman open flight data file. Win9000 inserts a marker in the profile at each data point that itdetermines to be a significant level. Regardless which data type—temperature orhumidity—is the reason for the significant level, both the temperature and humidityprofiles are accordingly marked. The same is true for wind speed and wind direction.Different styles and colors of markers can be selected, including lines that span the widthof the graph. (For instructions on how to select the marker styles and their colors and othersignificant level settings, see “Entering the Significant Levels Settings” on page 6-7.)Win9000 Processing and Display Software

The difference profiles allow you to compare the data setsfrom flights performed on the same day at the same time from two W-9000Meteorological Processing Systems. One of the profiles must be the base data set, and theother an active data set that has been added to the Flight window. For instructions on howto open a base data set and add active data sets, see “Displaying Data from Multiple FlightData Files by Adding Data Sets” on page 6-20. The profiles for a base data set are shownin Figure 6-14, and the profiles for an active data set in Figure 6-15. The base data set isthe first data set listed in the Active Data Set drop-down list box.The difference profile is generated by subtracting the values of each data point in theactive data set from each data point in the base data set at the same UTC time asdetermined by the base data set. If a corresponding data value in the active data set is notfound for a UTC time, the difference is not displayed. If there is no correspondencebetween the base and active data sets, no difference profile will be displayed. Thedifference profiles for the base and active data sets in Figure 6-14 and Figure 6-15 areshown in Figure 6-16 on page 6-23.To display the difference profiles for two data sets, select the active data set from theActive Data Set drop-down list box, right-click anywhere in the graph, chooseProperties from the pop-up menu, select the Display Difference Profiles option on theDisplay Options tab of the Graph Generator Configuration dialog box, and then clickOK.Win9000 Processing and Display Software
