Description

Description
When using network connection with EOS devices the satellite data is worng and doesn't match the data shown in EOS tools PRO. Mergin Maps shows only satellites in use and no satellites in view. But even this number jumps quite a lot and loops back to 0 after few values. Example logs below:

example_log_1.log

example_log_2.log

Environment
Production

Application (+ app version, build, operating system)
2026.3.0+

Steps to reproduce

  1. connect EOS receiver via network connection
  2. observe wrong data

Actual results
Wrong satellite info, doesn't match receivers proprietary app info

Expected results
Both satellites in view and in use are filled and matching receivers proprietary app info

Research direction

Start by examining the network-connection handling for EOS receivers and compare the two attached example logs with the satellite data displayed by EOS Tools PRO. Done means Mergin Maps reports stable satellites in view and in use, with values matching the receiver’s proprietary app.
