MA200 & MA500 Precision CHIRP Echosounder Altimeters - AUVAC

Innovative Products & Solutions for use in some of the world’s harshest environmentsMA200 & MA500Precision CHIRP Echosounder AltimetersThe OceanTools MA200 and MA500 precision echosounder altimeters containthe latest DSP electronics utilising frequency swept CHIRP technology toproduce altitude measurement with millimetric accuracy and resolution.The MA200 & MA500 units are 3000m depth rated as standard in hard-anodised aluminiumhousings. 6000m depth rated titanium units are available as an option.There are many applications for the altimeters, including:• ROV & AUV altitude measurement• Subsea lander altitude measurement• Under-ice measurement• Shallow water survey (see OceanPOLE on OceanTools website)• Monitoring sediment build-up (see MAAMS on OceanTools website)The altimeters provide numerous output formats including• RS232• RS485• Analogue• NMEA-0183 AltitudeKEY FEATURES200kHz and 500kHz units3000m and 6000m optionsCHIRP electronicsAnalogue & Digital outputs9 - 36VDC operationNMEA-0183 outputEchoView Software allowsLog & Replay of dataMillimetric range &resolutionMultiple units - up to 16 - may be connected together via a single twisted pair. Applicationsfor multiple altimeters include the lowering of large items to the seabed, monitoring canallocks and hydro-electric plants for sediment build up and for AUV navigation.OceanTools innovative EchoView software is supplied with the units which graphicallydisplays altimeter data as well as full logging & replaying of the data.
