1Introduction

UM960 is a new generation of GNSS high precision positioning RTK module from

Unicore. It supports all constellations and multiple frequencies, and can simultaneously

track BDS B1I/B2I/B3I + GPS L1/L2/L5 + GLONASS L1/L2+Galileo E1/E5a/E5b + QZSS

L1/L2/L5 + SBAS. The module is mainly used in UAVs, lawn mower, handheld device,

high precision GIS, precise agriculture, and intelligent drive.

UM960 is based on NebulasⅣTM, a GNSS SoC which integrates RF-baseband and high

precision algorithm. Besides, the SoC integrates a 2 GHz dual CPU, a high speed floating

point processor and an RTK co-processor with 22 nm low power design, and it supports

1408 super channels and realizes 20 Hz RTK positioning output. All these above enable

stronger signal processing.

UM960 features a compact size of 16.0 mm × 12.2 mm. It adopts SMT pads, supports

standard pick-and-place and fully automated integration of reflow soldering.

Furthermore, UM960 supports interfaces such as UART, I2C, which meets the

customers’ needs in different applications.

RF Part

The receiver gets filtered and enhanced GNSS signal from the antenna via a coaxial

cable. The RF part converts the RF input signals into the IF signal, and converts IF

analog signal into digital signals required for NebulasIV chip.

NebulasIV SoC

NebulasIV is UNICORECOMM’s new generation high precision GNSS SoC with 22 nm low

power design, supporting all constellations, multiple frequencies and 1408 super

channels. It integrates a 2 GHz dual CPU, a high speed floating point processor and an

RTK co-processor, which can fulfill the high precision baseband processing and RTK

positioning independently.

1PPS

UM960 outputs 1 PPS with adjustable pulse width and polarity.

Event

UM960 provides 1 Event Mark Input with adjustable frequency and polarity.

Reset (RESET_N)

Active LOW, and the active time should be no less than 5 ms.
