In this document, these will be referred to as the ADCPs. The tenderer is asked to quote for price each and provide delivery charges. Product Information: Current Profiling provided (ADCP mode) - required for both science data and for AUV navigation relative to water frame of reference. Communications interface which must be supported RS232, 19200 baud - compatibility with existing AUV system hardware and software. Unit Depth Rating is 6000m minimum - interchangeability between the AUV fleet. Power Supply Voltage Range supported includes range 24 volts to 48 volts - compatibility with existing AUV system hardware Weight in water is less than 20kg - affecting overall buoyancy and energy contingency. RDI PD0 output format supported - compatibility with existing AUV software. Materials suitable for long term (1 year) submersion in sea water (e.g. Titanium or plastics) - long term AUV deployments. Bottom tracked (or from ice ahead) dead reckoned navigation is critical for successful missions. The AUV will be required to operate in a variety of water depths and AUV depths. Greater bottom track ADCP range gives greater operational flexibility. Compatibility with existing software. Without this the levelling software will need developing and testing. For system speed of sound correction (given fixed salinity information). If included, this reduces software and system development effort. Lower peak power simplifies the design of the AUV power supply system. Less weight means more payload or batteries can be carried
