Alps Electric has developed the UMSZ2 Series multi-GNSS module for automotive use, providing support for multiple satellite positioning systems with a single module. Samples will be made available starting in April.

The module can receive signals from multiple GNSS, allowing simultaneous reception of signals from multiple positioning systems with the single unit. 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, realizing the industry’s fastest time to first fix.

Furthermore, the UMSZ2 Series can operate off a single 3.3V power supply despite simultaneously receiving signals from multiple GNSS. Eliminating the need for a multiple power supply contributes to greater freedom in system design.

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.
