The OSR uses a FPGA & processor combination that integrates the software programmability of an ARM®-based processor with the hardware programmability of an FPGA, enabling key analytics and hardware acceleration while integrating CPU, DSP, ASSP, and mixed signal functionality on a single device.
The overwhelming advantage with our designs is that the functionality in the receivers is largely defined in firmware and software. This allows for relatively simple and low cost development cycles that can be frequent. It inherently allows for adaptation to special needs in niche markets. For example; custom tracking loops for high dynamics or for atmospheric scintillation studies, tracking of pseudolite signals from other devices. Other specializations include multipath mitigation techniques that may require special correlations, optimization for quick reacquisition, or for tracking of weakened or spammed signals. A major current customization is the integration of MEMS data that can be done all the way to tight integration through firmware and software alone.
A number of software/firmware combinations (only limited by available memory) can be stored onboard and be loaded as requirements may shift. In space applications we can for example use an optimized set for atmospheric studies and then load an other set to support docking maneuvers. A ship has different navigation needs in harbor and at sea. In some applications such as communication stations or radar units, Time-synchronization may be the main application except when equipment is repositioned. A general purpose PNT receiver can do both but with our designs it's possible to dynamically adjust and optimize solutions for improved performance and/or lower costs.
These are important advantages over rigid designs that are typically optimized for land surveying, are suboptimal for machine control and for many other emerging markets. These advantages come at a cost so our solutions may not be suitable for unit cost sensitive high volume applications unless upgradeability and flexibility is important. For such applications, we present the OSR as a development platform that may result in implementation of the final design in ASIC. DataGrid can assist in such developments and can also port and license its firmware and software solutions.
The OSR returns the advantage to the small and cost sensitive developer. It will bring the advantage of tailored and optimized solutions to the end user. Our expectations are no less than a game change in the high performance PNT market. 85˚C
