Our photo sensor has the following trigger light response speeds: Turn-On time: 8 uS (microseconds) Turn-Off time: 50 uS (microseconds) This trigger recording speed sent and recorded by the M2 is sufficient to ensure centimeter accuracy, taking into account the drone's flight speed margins in a topographic survey flight mission.

All work in PPK mode must have Ground Control Points. The number of points will be subject to the work area. We recommend placing only 30% to 40% of the control points that would normally be used in a conventional survey. For example: 20 points in conventional mode to 5 points in PPK mode. These points will serve to make a control in x,y,z.

In some specialized processing programs such as Toposetter 2.0 Pro and REDToolbox, x, y, and z values can be set to compensate or correct for the offset of the antenna-to-camera distance before starting post-processing.

By using its own battery, the kit does not affect or reduce the flight time of the drone. However, as a general rule for high altitude flights, it is recommended for safety reasons to set the drone's internal battery consumption alarm to 30% and with return to take-off to 25%. Please check the drone's user manual for these settings. Always use drone batteries in good condition.

The materials from which the PPK Kit Mavic 2 and 3 airframe is constructed (ABS-PETG polymers) and all the electronics inside, are resistant to very harsh working environments, with outside temperatures from -5°C to 80°C (23°F to 176°F). Please note that the operating temperature range of the Mavic 2 drone is only from 0°C to 40°C (32°F to 104°F).

The maximum capture or positioning register frequencies of the modules are as follows: M2: 10Hz (10 records per second). Based on these characteristics, in order to achieve maximum accuracy in positioning data capture during drone flights, we can recommend the following: [1] Select the highest possible frequency according to the number of GNSS systems required. For example: In the M2 module: GPS + GLONASS, frequency 10Hz. [2] Fly in mode: "Hover & Capture at a Point" (Speed can vary between 3m/s to 15m/s). [3] If you fly in "Capture at Equal Distance Interval / Time Interval" modes, the drone speed should not exceed 5m/s. Remember that the higher the flight speed the accuracy range may decrease, so the speed should be as low as possible according to your availability of operating time and batteries. [4] Regarding the flight schedule, it is recommended to fly in the hours when the height of the Sun above the horizon is ≥45 degrees sexagesimal. [5] Image overlap: According to the type of terrain. Flat terrain: Longitudinal: 60%. Lateral: 20%. Undulating terrain: Longitudinal: 70%. Lateral: 30%. Mountainous terrain: Longitudinal: 80%. Lateral: 50%.
