Multi GNSS module targets automotive applications

March 31, 2014 // By Jean-Pierre Joosting
ALPS ELECTRIC EUROPE GmbH has developed the “UMSZ2 Series” multi GNSS module for automotive use, providing support for multiple satellite positioning systems with a single module.

Because the positioning accuracy of satellite positioning systems can be improved by receiving signals from a large number of satellites, there is demand for modules that support multiple positioning systems. Some countries are even considering mandatory customs duties on products that are not compatible with their own positioning systems. Consequently, there is a growing requirement that product components also support multiple positioning systems.

Recognizing this need, the UMSZ2 Series multi GNSS module can receive signals from multiple GNSS. The module even allows simultaneous reception of signals from multiple positioning systems.. It is a surface mount module with dimensions of 25.0 × 20.0 × 2.6 mm. Also equipped with an internal antenna status detection circuit, as required for GNSS signal reception, the module helps to reduce the customer’s workload in designing and installing such circuits.

ALPS Electric harnessed RF circuit and software design technologies built up over the years to optimize the UMSZ2 Series’ circuitry and create a single-package multi GNSS module. The time taken to acquire a position fix after turning on the system was also shortened, claiming to be the fastest in the industry.

Furthermore, the UMSZ2 Series can operate off a single 3.3 V power supply despite simultaneously receiving signals from multiple GNSS.

A dead reckoning function for updating position information inside tunnels or in other areas where a signal is unavailable will also be added as an option.
