New L-band Receiver from u-blox Enables Centimeter-Level Positioning
February 27, 2020
The NEO-D9S GNSS correction data receiver module can receive GNSS correction data from correction service providers broadcast on the L-band (at 1525 ? 1559 MHz).
u-blox announced its new NEO-D9S GNSS correction data receiver module that receives GNSS correction data from correction service providers broadcast on the L-band (at 1525 – 1559 MHz). A host processor can then decrypt this correction data and provide it to a GNSS receiver, combining corrections directly with readings from the satellite constellations to enable accurate position readings, according to the company, than those offered by GNSS signals alone.
According to the company, use of the NEO-D9S will also increase the availability of high precision GNSS positioning data in areas with limited connectivity and reduce the amount of cellular data consumed by positioning receivers.
The NEO-D9S module is a correction-only receiver, based on the latest u-blox 9th generation (D9) platform. This means that it will integrate easily with the u-blox F9 RTK GNSS receivers from u-blox, or can be used as part of a modular product roadmap. The module also integrates a TCXO and SAW filter to ensure good RF sensitivity and resilience to interference from adjacent channels.
The module includes the algorithms necessary to decode satellite data broadcasts. It is configured to work initially with whichever correction service has been set as default, but can be configured for any L-band data broadcast. It stores its configuration settings in non-volatile memory.
