Hi Team
I'm enquiring about which product would be most suitable for my problem. I'm working on a university project to automate a stationary telescope by using a GNSS module to provide accurate heading and pitch data. We aim to achieve an accuracy of at least 0.5 degrees in each direction (heading and pitch).
We have a publicly available RTK base station within 200 meters of our installation site if RTK technology is necessary to provide accurate heading information, or we could consider setting up our own.
I am looking at the UM982 modules, specifically reference number ELT0213. Dual antenna systems seem to provide accurate stationary heading information. Does this device still require RTK to obtain accurate heading information? If so will 200 meters away from the base station be able to provide good accuracy?
What solution would you suggest?

Hi Olaf,
As you need only angles and not the precision positioning of you telescope, you does not need RTK at all. I hope that your telescope base is stationary. So if you need heading and pitch, you need to setup two dual-input modules with two antennas for each. Distance between antennas will define precision of the measurement. The approximate course standard deviation is 0.25 degrees for an equilateral triangle with a one-meter side. So, it will be the best, if you can setup at least 2 m distance between antennas in both heading and pitch directions.
