Description

UM980 All-constellation Multi-frequency High Precision RTK GNSS receiver.

UM980 is Unicore’s new-generation proprietary high-precision RTK positioning module based on the Nebulas IV SoC which integrates RF, baseband and high-precision algorithm. The built-in multi-frequency anti-jamming technology enhances RTK calculation on multiple modes and frequencies, which significantly improves RTK initialization time, measurement accuracy and reliability in complex environments such as city blocks and tree shades. Relying on the excellent performance, UM980 is well suited for high-precision navigation and positioning applications such as precision agriculture, surveying and mapping and so on.

Recently received this unit to replace my similar f9p setup. With a high quality triple band antenna and a clear sky I'm getting 91.8 quality score on onocoy. This is even better then the 80-90 numbers I was expecting.

Note:
You will want to use a high quality power supply I'm using a raspberry pi 5 27w rated power supply but this might be a little overkill.
