Instant telemetry rate is 500bits/sec. Effective rate is 160 bits/positioning cycle. Positioning
cycle is majored by 5sec to let the transponder time to process the request (sensor meas-
urement, fix INS...). For example, if you are positioning an AUV with a positioning cycle of
2 seconds, when telemetry is transmitted to the AUV, the positioning cycle will be 7 seconds.
Gaps M5 can be use from a few meters to 995m range. Even in reflective environement
and very short range less than 10m, the performance will be nominal.
No, Gaps M5 is an export free system. Gaps M7 is the solution for longer range tracking.
There is a little accuracy decrease with the elevation angle, especially in the target depth
estimation. Tilting the Gaps M5 is possible up to 45° but the accuracy gain is not huge.
Maximum positioning update rate is 1.25Hz (0.8sec cycle)
Gaps M5 does not need calibration at all. The mechanical design alone allows for 0.5% of
the distance.
Gaps M5 is calibration free and do s not require any calibration at sea. However, it is pos-
sible to change each hydrophone vertical offset (value in mm), this value is preset in factory.
Each spare hydrophone is deliverd with a vertical correction offset to be entered in the Gaps
MMI.
