Description

UM980 All-constellation Multi-frequency High Precision RTK GNSS receiver with onboard patch antenna, LIS3MDL magnetometer and noise protection

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 module supports GPS L1C/A/L1C/L2P(Y)/L2C/L5, BDS B1I/B2I/B3I/B1C/B2a/B2b, GLONASS G1/G2/G3, Galileo E1/E5a/E5b/E6, QZSS L1C/A/L1C/L2C/L5, NavIC L5 and SBAS L1C/A. 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.

Hey
I am interested in the ELT0227 - UM980 GNSS receiver with the multi-band antenna.
- Is it possible to power the board via the I2C port?
- I noticed that the antenna supports the E6 frequency bands. What PPP convergence time can I expect with Galileo HAS compared to your ELT0316 - All Bands High Performance RTK GNSS Active Quad Helix antenna?


Shop owner reply (28/01/2025):
Dear Josef
"Is it possible to power the board via the I2C port?" - Do you mean powering the receiver via the 4-pin J2 port to communicate with the magnetometer? No, there is no +5V contact on J2. It is only on the 12-pin J1 port.
"What PPP convergence time can I expect with Galileo HAS compared to your ELT0316" - The convergence time under ideal conditions depends very little on the antenna, if the antenna receives all signals and has a small phase center. The ELT0227 uses the ELT0193 antenna https://gnss.store/gnss-rtk-multiband-antennas/266-elt0193.html

In real life… Helix antennas filter out reflected signals better. Patch antennas work well with a large groundplane, for example on a car roof.
If you have multipath (reflected signals) in the upper hemisphere - helix is better. In the lower hemisphere (reflected signals from the ground) - patch + groundplane.
