R-PNT Project: Resilient Positioning, Navigation & Timing

A new requirement during the last decade is the Positioning, Navigation and Timing (PNT) during military operation and in GNSS-denied environment. In order to improve size, weight and power (SWaP) of equipment, the department of National Defense of Canada is looking for better performance systems with the lowest possible weight, power consumption and critical operational efficiency. When GNSS signal is jammed, PNT alternative solutions are suitable feedbacks, essentially based on inertial sensors and dead reckoning algorithms, as well as the use of Signal of Opportunity (SoOP) when GPS timing and positioning is critical in operational theaters, during targeting, tactical reconnaissance and surveillance, real time tracking of soldiers, etc. A high reliable PNT solution is required to maintain the operation ability of the military forces and the synchronization with the command centers and weapons management systems.
The objective of the project is to provide a complete multi-IMU (Inertial Measurement Unit) solution on the Body-Suit (ibNav Project), a new technological solution with more advanced multisensory integration (accelerometers, gyroscopes, magnetometers, baro-altimeters, heart rate, blood pressure, etc.) and personalized algorithms. Robust data fusion (Kalman filtering based) allows the soldier trajectory to be tracked in real time with health monitoring data streaming to the commander control terminal. More than inertial sensors, pedometer algorithms, high accurate motion tracking, and reliable navigation solution is maintained by the use of SoOP in GNSS-denied environment. LEO satellite Doppler based and carrier phase based ranges are integrated to the Global-Body-Skeleton Multi IMUs data fusion to compute total PNT solution requested during critical military missions and operations.
