it synchronization (clock lock) The condition achieved when significant transitions of the recovered data rate clock are phase-stable to within 25 percent of the bit period. blocked service A queued service held from scheduling, awaiting (1) the availability of participating terminals busy with other services, or (2) the completion of setting up the path for a multiple-hop service. building block A fundamental unit of channel time used in determining time within a frame. Used in the assignment of channel resources. burst A time-limited transmission composed of a synchronization preamble and a finite-length data stream that are formatted into interleaver block pairs. burst code A combination of modulation rate, coding rate, and (for message services) maximum burst size. burst rate The over-the-air transmission rate (modulation rate) in symbols per second. bus The body of a satellite. The bus holds all of the scientific equipment and other necessary components of the satellite. The bus of a satellite is made of a variety of materials that are selected to protect the satellite from things like collisions, a build-up of electric charge, extreme temperatures, and radiation. carrier The basic radio, television, or telephony center of frequency transmit signal. The carrier in an analog signal is modulated by manipulating its amplitude (making it louder or softer) or its frequency (shifting it up or down) in relation to the incoming signal. Satellite carriers operating in the analog mode are usually frequency modulated. carrier acquisition The condition achieved when a receiver carrier reference is coherent in frequency and phase with the receive signal. carrier frequency The main frequency on which a voice, data, or video signal is sent. Microwave and SATCOM transmitters operate in the band from 1- to 14-gigahertz (GHz) (a GHz is one billion cycles per second). carrier to noise ratio The ratio of the received carrier power and the noise power in a given bandwidth, expressed in dB. This figure is directly related to G/T (antenna gain-to-noise temperature in dB/K) and signal/noise (S/N); and in a video signal the higher the C/N, the better the received picture. cassegrain The antenna principle that utilizes a sub-reflector at the focal point that reflects energy to or from a feed located at the apex of the main reflector. channel A frequency band in which a specific broadcast signal is transmitted. The Federal Communications Commission specifies channel frequencies in the United States. Glossary-11
channel control orderwire channel control orderwire acquisition channel control orderwire time-slot Glossary-12 The transmissions from a controller that control the waveform and its usage, such as frame number, encryption synchronization counts, user time-slot assignments, and frame format in current use. The terminal’s status when it has successfully achieved error free reception of a CCOW: Master Frame (checked by CRC). The time-slot through which a terminal receives CCOW transmissions. channel controller A generic term that relates to either a primary or alternate controller. channel resources The available time, bandwidth, and power of a channel. circuit burst kind A field that identifies the type of burst being transmitted during a circuit service. circuit number A 5-digit decimal number that identifies a time-slot when operating in the DC mode. circuit service Channel resource assignments in each frame that are dedicated for use by participating members for duration of the assignment. C/kT The ratio of the rf carrier power (C) relative to noise power density. Carrier power is measured into the receiving system. k = Boltzman's constant and T = the effective noise temperature at the terminal antenna in kelvins. coherent demodulation A demodulation process characterized by a synchronized, phase-matched condition between a receiver's reference and the received signal. connected The configuration of a channel controller in which connectivity to adjacent satellite footprints by relay is available. connectivity The physical infrastructure required to allow access and exchange of electronic information. contention-return orderwire time-slot continuous phase modulation A ROW segment time-slot available for use by any terminal that has achieved downlink acquisition. The possibility exists that transmissions from multiple terminals occurs in the same time-slot. A phase-only modulation technique in which the signal phase changes are continuous. Phase changes for each symbol are odd integer multiples of the modulation indices hi. For multi-h CPM, the indices cyclically change from symbol to symbol in order to provide coding gain to the waveform. control channel A 25-kHz DAMA channel on which a channel controller (CC) transmits CCOW messages and the frame is segmented for terminals to transmit RCCOW, link test, ranging, and user communications signals.
