Reach Single solution accuracy

[TB_RTK]

@cczeets

@TB_RTK You can’t post-process a single REACH “all alone”. That would be what @mikhailavkhimenia said as standalone position, ~2-5m accuracy. When you post-process, you are always processing to another GPS receiver on a known point. Whether that be a point with a GPS already running on the monument (i.e. those providers you mentioned), or not. If you are in the U.S., you can take advantage of the CORS network. Your other option is to find an already know reference monument (typically an NGS monument) and setup a REACH in STATIC mode on that, then post-process to the point you want to set “in the middle of somewhere”. The REACH can get a cm accuracy position up to 10km away with ~10 minutes of RINEX data, depending on sky/satellite conditions. If you want to go farther than that, then you need much longer observation times (hours) or an L1/L2 receiver (if you want to achieve cm accuracy).

Hope that helps!

Best,

Are you sure?
When i read this , it sounds like i can get a more accurat solutions by submitting my single data to this site and get a more accurate solutions.

CSRS-PPP is an online application for GNSS data post-processing allowing users to compute higher accuracy positions from their raw observation data.

CSRS-PPP uses the precise GNSS satellite orbit ephemerides to produce corrected coordinates of a constant “absolute” accuracy no matter where you are on the globe, regardless of proximity to known base stations.

Users can submit RINEX observation data from single or dual-frequency receivers operating in static or kinematic mode over the Internet and recover enhanced positioning precisions in the Canadian Spatial Reference System (CSRS) and International Terrestrial Reference Frame (ITRF).
