Reach RS2 / RS2+ RTK / PPK configuration

Hi has anyone been tinkering around with Ginan and Emlid receivers using their NTRIP? RTCM SSR Correction Stream (1059, 1060)

I did glance at it some time ago and it appears still in a bit of a Beta phase. Looking at it again now, it seems 1060 messages are sent every 10 seconds, so maybe not practical for RTK? How this mount point works with a GNSS Rover though I have not looked into yet.

Good cheat sheet here

Hi @jason4,

Nice to see you back!

We haven’t tested the Ginan service with our Reach units, but generally, they support RTCM3 messages. For accurate solution computation, it’s important to include messages with the Antenna Reference Point (ARP) and Multiple Signal Messages (MSM). Commonly, these messages are 1006, 1074, and 1077.

You might find a list of supported RTCM3 messages in this thread useful.

Thanks for your response - I have an pair of RS+ - they look to be unavailable

Could you please elaborate on it? Are they not showing up in Emlid Flow or not connecting to your NTRIP service?

Having mounted to it this morning before starting a job, it appears it is not compatible.

Perhaps Ginan is a product better suited to augment the location for other types of GNSS devices?

Hi guys,

I checked with the team and reviewed the available resources. Based on what we found, it seems Ginan might work as follows:

You run the Ginan software and provide it with data streams from the GNSS receiver (observation data) and SSR data. The SSR data likely includes messages 1059 (Bias) and 1060 (Correction). Ginan then processes these inputs to give you an accurate position.

I believe it’d be better to double-check this with Ginan’s support team to make sure we’ve got it right.
