I have been using the Reach RS+ with local NTRIP with good success. I recently purchased ardusimplertk2b as I needed a base for my Mavic 3E. I wanted to use the Ardusimple as my base also for the RS+ and was using rtk2go. I however cannot get a fix or even a float sollution with this setup. I have confirmed the base is setup correctly as the Drone connects fine. I have viewed the RTMC messages using snip and even added in a 1008 message as a safety. My RTMC messages appear to match my local NTRIP providers and as soon as i chnage over the corrects i achive a Float then usually Fix a short while after. While i have a M+ that works fine as a base for the RS+ i was trying to cut down my setup time. Is anyone else striking this problem. I have searched and it seems there is mixed problems intergrating different brand GPS units. If anyone can point me to diffinitive RTMC messages required as start that would be helpful. Currently have a 1005, 1008 added in, then MSM4 messages as that is what my NTRIP provider is sending out and I can get a fix on. I see the base will send MSM7 so assume it would also accept that which I have tried to no avail.
To get your Reach unit computing solutions properly, you usually just need to input messages with the Antenna Reference Point (ARP) and Multiple Signal Messages (MSM). Typically, these include messages like 1006, 1074, or 1077. I remember seeing a list of supported RTCM3 messages in this thread.
So, why did adding messages 1005 and 1008 make a difference for you? Here’s the scoop:
1005 gives you the coordinates of the Antenna Reference Point (ARP).
1006 includes everything 1005 does but with the antenna height added.
1007 provides details about the base station antenna type.
1008 is like 1007 but also includes the antenna’s serial number.
The Reach units also support MSM4. Generally, the higher the MSM number, the more info you get. For example, MSM1 covers code measurements, while MSM3 includes both code and phase measurements.
Your Ardusimple SimpleRTK2B is a multi-band receiver, whereas the Reach RS+ is a single-band one. You can use it as a base for your Reach RS+ but you won’t get the advantages of working with multi-band receivers with such a setup. The base will send L1, L2, and L5 signals, but the Reach RS+ rover can only receive L1 signals. So, it’s pretty much the same as using two Reach RS+ units in terms of signal reception.
