The BU-1025TF is built on the ultra-low power UBX M10 GNSS platform, which provides exceptional sensitivity and acquisition times.

 

The extremely low power consumption of less than 25mW in continuous tracking mode allows great power autonomy for all battery-operated devices, such as asset trackers, without compromising GNSS performance. The BU-1025TF supports the reception of GPS, GLONASS, Galileo, and BeiDou. The high number of visible satellites enables the receiver to select the best signal. This maximizes position availability, especially in challenging conditions, such as in deep urban canyons.

 

The BU-1025TF adopts super-S technology, which offers great RF sensitivity and can improve the dynamic position accuracy by up to 25% with small antennas or in a non-line-of-sight scenario.

 

The BU-1025TF module integrates an LNA and a SAW filter in the RF path for maximum sensitivity in passive antenna designs. BU-1025TF offers a cost and power-optimized setup without LNA and SAW filters. Advanced filtering algorithms mitigate the impact of RF interference and jamming, thus enabling the product to operate as intended.
