Tiny RTK Setup - setup files?

Hi Drotek,

i use two tiny-rtk modules for Base and Rover Setup.
U have newest firmware .140 installed,
i use u-center 18.11
I do not use telemetry nearby gps antennas.
telemetry power is reduced to minimum. 915MHz

Antennas are outside, reveivers inside. 1m from each other,
we have ground planes, and high sky visibility.

I got 3d/GNSS/FLOAT - but very unstable Fix.

Because there are so many possible configurations I am searching
for two setup files for setting up base and rover to avoid erratic configurations.



A well-placed antenna is crucial to achieve good RTK positioning results

You can place your smartphone near the window in your house and it will obtain GPS coordinates after some time, but for RTK such environment won’t be sufficient. For RTK to work there are special requirements for antenna placement that are much more strict that for a standalone GPS.

No obstacles blocking the skyview

Antenna needs to have a clear skyview 30 degrees above the horizon. There should be no obstacles that could block the view like: buildings, trees, cars, humans, laptops etc.

Examples of bad environments for antenna placement: indoors, urban areas, forest, close to the ground.

Examples of good environments for antenna placement: field, top of the hill, rooftop of a building.

No electronics nearby

Electronic devices may produce RF noise that could affect reception of the GPS signal. Keep all electronics (including the Reach itself) as far as possible from the antenna.

Ground plane

Antenna has to be placed on a ground plane which reduces multipath, provides shielding and improves signal reception. Ground plane is a conductive plate, it may be a piece of metal, a roof of a car, a metal roof of a building, etc.

Tallysman TW4721 requires ground plane no less than 70x70mm.
