USCG Exam PracticeGPS and electronic navigation
A satellite navigation receiver required by 33 CFR §164.41 must meet two specific functional requirements. Which pair correctly states both requirements?
- ✓ Automatic acquisition of satellite signals after initial operator settings have been entered, and position updates derived from satellite information during each usable satellite passCorrect
- B. Continuous position display without any operator input, and accuracy within 10 meters CEP at all times
- C. Automatic acquisition of satellite signals without any operator input whatsoever, and a backup battery capable of 24-hour operation
- D. Position updates at intervals not exceeding 60 seconds, and automatic alarm when satellite geometry degrades below a set HDOP threshold
Why A is correct
33 CFR §164.41(a)(1) and (a)(2) specify exactly two functional requirements: automatic acquisition of satellite signals after initial operator settings have been entered, and position updates derived from satellite information during each usable satellite pass. The other options introduce accuracy thresholds, battery backup, update intervals, and HDOP alarms that are not stated in the regulation.
