When does the sensor start and stop collecting data?

2p Sensors

2p sensors start collecting data when the light on the AIS blinks green. As soon as power is connected the sensor boot sequence begins:

1. As soon as power is connected, the sensor will start bootup. The solid green light comes on while the sensor is initializing. MAKE SURE THE AIS IS NOT SHADED DURING BOOTUP, AND HAS A CLEAR VIEW OF THE SKY.
2. Green and yellow lights flash for a few seconds.
3. The yellow light flashes while the system acquires GPS.
4. After finding GPS lock, the yellow light stops flashing and the green light starts flashing about once per second.
5. When the green light is flashing, the system is collecting data. Wait for the system to start collecting data before taking off.
6. Press the AIS button upon landing to complete a data collection

3p Systems

3p sensors begin collecting data after the user presses the AIS button

1. As soon as power is connected, the 3p will begin bootup. Cycling green, red, and yellow lights will be displayed on the AIS. (If a red light is displayed on the AIS, there is a memory card error. Use the 3p Toolbox to reformat)
2. After a few seconds, the AIS lights will turn to solid green, yellow, and red indicating successful bootup.
3. Press the AIS button to begin the data collection. MAKE SURE THE AIS IS NOT SHADED DURING BOOTUP, AND HAS A CLEAR VIEW OF THE SKY.
4. When the green light is flashing, the system is collecting data. Wait for the system to start collecting data before taking off.
5. Press the AIS button upon landing to complete a data collection. The sensor will return to standby mode, showing solid green, yellow, and red lights on the AIS.
