General Description:
The GM900 is built on the robust u blox M9 GNSS chip, which provides exceptional sensitivity and acquisition ti mes for all L1 GNSS systems. The u blox M9 standard precision GNSS platform, which delivers meter level accuracy.
GM900 supports concurrent reception of four GNSS. The high number of visible satellites
enables the receiver to select the best signals. This maxi mizes the position accuracy, in
particular under challenging conditions such as in deep urban canyons.

Performance |
- All value are defined at 25±15°C ,65±20 % RH.
- Patch characteristics are measured with 70x70 mm ground plane in an anechoic chamber.
- All satellites at -130 dBm,except Galileo at -127dBm.
- Dependent on aiding data connection speed and latency.
- Demonstrated with a good external LNA.
- CEP, 50%, 24 hours static, -130 dBm, > 6 SVs.
- 50% @ 30 m/s.
- Assuming Airborne < 4 g platform.

Evaluation software
|
The u-center software installation package for the GM900 can be downloaded from the Web:
www.u-blox.com/en/evaluation-software-and-tools.
Once the zip file is downloaded and unzipped, unzip the file in Tools folder and double-click the extracted exe file. The software components will be installed on your system and placed under the “u-blox” folder in the “Start Programs” menu.
u-center is an interactive tool for configuration, testing, visualization and data analysis of GNSS receivers. It provides useful assistance during all phases of a system integration project. |
