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.

All docs are on the SD Cards ( Sd card, is not destroyed, if you put it inside the smartphone to read the PDF ) but you'll need a PC to setup the Wifi. Wifi is OK when light is red, gps is ok when light is Green ( blink is not good ). The Wifi lock to an existing AP ( AP2 or AP do not care ). You do not need external Power to setup &amp;amp;quot;USB-C&amp;amp;quot; make the job. you cannot connect to USB they remove &amp;amp;quot;Echo&amp;amp;quot; do not try you'll get crazy... philosophy is : &amp;amp;quot;Wifi&amp;amp;quot;. not 5 stars because : Please Add the 1Euros MicroSD to SDCard !!! in some country this is very hard to find. please add a A4 Paper in the boxe &amp;amp;quot;Picture of the system working&amp;amp;quot;, and the lines, i write above...


Shop owner reply (07/05/2025):
Dear Eric
1) You are right, we are really late with the documentation.. Preliminary version - https://eltehs.lv/ELT_RTKBase_v1.8.0_EN.pdf

2) The documentation will be available in a few days at https://gnss.store/blog/category/elt-rtk-base.html and the link to it will be in the product card.

3) Connecting to WiFI - wait for the "Internet" LED to blink and press the WPS button on the access point. Unfortunately, this was not in the old documentation.

4) The USB connector is the receiver connector. You can update the firmware through it using UPrecise.

5) Instead of an adapter, maybe a USB card reader would be better?
