DO NOT use a 2p or 3p AIS cable or power cable with your 1p sensor. The 1p sensor power cable is made for a 4V single cell power supply. 2p and 3p sensors take up to 24V six cell power supplies.
1p Flight Metrics
Image overlap (along-track) is a function of the data collection rate of the sensor, the size of the image on the ground at the given flight altitude, and the flight speed of the aircraft. The sensor is collecting images approximately once per second, so the distance the aircraft travels in one second should not exceed 80% of the image’s along-track dimension.
Many flight planning software packages will automatically space your flight legs when given the parameters of the imaging system and the required sidelap. The sidelap for a 1p sensor should be 20% to 30%. See the tables for image size, recommended maximum speeds at various altitudes, and optical parameters of the 1p system oriented nadir.
Note: If flying a multirotor, you must angle the sensor mount to compensate for aircraft pitch at the chosen speed.
