Choosing which GPS constellations to view/use #43

Description

@adams050

I am the owner of both an NTP250 and an NTP200. Both have their antennas placed with clear sky views, and are roughly 8 inches apart. The antennas have identical labeling. Both NTP units have been running for the same number of hours. I live in eastern Minnesota.

My issue is the discrepancy between the satellite constellations listed by the two units. As seen in the accompanying GPS Details screen grabs, both units see mostly the same satellites. However, only the NTP200 sees the Galileo constellation. I would like to see the BeiDou constellation, along with the other three (GPS, GLONASS, Galileo).

I have experience with another u-blox antenna/receiver, controlled by u-center software. See the third screen grab for the description of that unit. Notice also that "all-constellations-viewing-at-once" is not possible. Only certain combinations are allowed. The u-center software (version 21.02) controls the constellation choices via the GNSS Config command.

Will it ever be possible for the NTP2x0 units to choose which constellations are used/displayed? I suspect my two units' u-blox GPS receivers were initialized differently. Can they eventually be controlled/changed by the end user?
