Question

Hy.

I try to use the gps data from RUT955 via modbus and I have some concerns:

1. Register number 183 "GPS accuracy" what is about, is that meters?

2. Register number 147 "GPS fix time" looks like it take into account the time zone from router in a wrong way (if time zone is +2 the gps fix time will be gps time - 2).

Firmware from the router: RUT9XX_R_00.06.03.2

Best regards!

Hello,

1. In RUT955, "GPS accuracy" parameter (which's value you can see via Modbus or SSH) is representing DOP (Dilution of precision) value. Basically it can be considered as additional multiplier, which multiplies router's GPS accuracy (which is 5 meters). More information about DOP can be found online, e.g. here:

https://en.wikipedia.org/wiki/Dilution_of_precision_(navigation)

So the final GPS accuracy is DOP value ("GPS accuracy" parameters value) x  5 meters

2. Thank you for letting us know the issue about displayed "GPS fix time" value. We will address this issue in upcoming firmware release.
