Hi, I would like to buy two Reach M2 devices for a personal project but I have some doubts to clarify (I hope this is the right place). The two Reach M2s should be positioned on the two sides of a vehicle and should store position data that can be used together with other sensors. I read on the product page of the two modes of operation RTK and PPK. In my case, RTK would be preferable, passing the data in real-time on a Windows PC in the vehicle via the serial port. But I have some doubts about the RTK mode that I would like to clarify with you:
- In RTK mode there is a base station to connect the M2s to and thanks to which greater accuracy can be obtained. How do the M2s communicate with the base station and what kind of range can be achieved with the M2s in motion (maintaining centimeter accuracy)?
- Are the corrections on the axes that are applied to the position supplied as data (IMU) applied directly to the output data in RTK / PPK or is there a need for post production?
- Can I use other alternatives besides the serial port to exchange data with Windows in RTK mode? I was going to use Python
- If I choose to rely on an NTRIP service, is it possible to connect the M2s to the internet via smartphone or is a cellular module required for each M2?
- Also on the site I saw that through the Android application you can set the output of the M2, for example serial port. Is it an operation that must be repeated at every start or is the M2 able to memorize this choice?
