GPS Module PA1616D for AudioMoth Dev, 'D' model 99 acquisition-channel GPS + GLONASS receiver compatible with AudioMoth Dev.

 

The standard AudioMoth firmware supports the use of a connected GPS receiver to update its real-time clock, and to measure the precise sample rate, before each recording period. This allows events within a recording to be assigned a timestamp that is accurate to within a few milliseconds with little increase in overall energy consumption. In many applications, this level of time synchronisation is sufficient. However, sometimes more precise time synchronisation is required. For example, when the source of acoustic events must be localised to high accuracy. In these settings, AudioMoth GPS Sync can be used. This solution consists of alternative firmware that powers the GPS continuously whilst audio recordings are being made. This increases the energy consumption of the recording process, but also allows the AudioMoth to continuously track and record the arrival of pulse-per-second signals from the GPS module. An associated desktop app then performs post-processing of the recorded data to generate synchronised WAV files that are aligned with GPS time to better than 1 microsecond.
