SRX SRX-SW-Defined Receiver for Exact PNT

The SRX project had the primary goal of creating an industrial prototype for a multi-GNSS multi-frequency GNSS receiver module. This module is designed to deliver highly precise positioning and heading capabilities even in challenging signal environments like dense forests. To achieve this, the project focused on integrating Galileo E5ab and BeiDou-3 B2 ACE-BOC wide-band signals with MEMS sensor measurements, which is seen as a crucial step toward developing robust vector tracking solutions for dependable high-precision Positioning, Navigation, and Timing (PNT).

New hardware

In addition, the project places significant emphasised on incorporating the latest advancements in hardware technology. This includes state-of-the-art RF-ASICs, digital processor System-on-Chip (SoC), MEMS technology, and clock systems to ensure the long-term availability and reliability of the product. The system’s scalability is also a priority, enabling it to adapt to the growing number of GNSS satellites in orbit. Furthermore, the system’s flexibility in implementing complex signal and navigation processing algorithms is essential for a successful system design.

New RTK solution

However, the core of the system lies in its sophisticated Real-Time Kinematic (RTK) enabled vector-tracking algorithmic solution, which pushes the boundaries of current technology. To minimize the associated development risks, the project included hardware and algorithmic prototyping as integral components.
