Multi-Band, Multi-Constellation, Centimeter-Accurate GNSS
The Piksi Multi GNSS receiver from Swift Navigation. Its dual-frequency operation offers fast RTK convergence times and reliable, centimeter-accurate results at a breakthrough price.
Centimeter-Level Accuracy
Autonomous systems require precision navigation—especially those that perform critical functions. Swift Navigation solutions utilize real-time kinematics (RTK) technology, providing location solutions that are 100 times more accurate than traditional GPS.
Fast Convergence Times
Multiple signal bands enable fast convergence times to high-precision mode. Single band RTK systems converge in minutes, while Piksi Multi converges to a high-precision solution within seconds. This allows for much faster system start times, as well as faster reacquisition, which is critical to robotic systems.
Robust Positioning Performance
Piksi Multi supports GPS L1/L2 and GLONASS G1/G2 for RTK measurements and positioning and SBAS for robust sub-meter positioning in non-RTK mode. Additional constellations create more robust positioning performance in a variety of challenging skyview environments. Integrated MEMS oscillator technology enhances robustness under vibration and shock. Integrated MEMS IMU technology allows for sensor fusion techniques that enhance positioning performance.
Open Platform
Piksi Multi features a powerful Xilinx Zynq® processor with an FPGA and dual-core ARM® Cortex®-A9 processors. Plenty of computational headroom and on-board Linux enable seamless integration of customer applications.
Rapid Prototyping
Piksi Multi is designed to be easy to use. The Piksi Multi Evaluation Kit includes: 2 Piksi Multi GNSS modules; 2 integrator-friendly Evaluation Boards; 2 GNSS survey grade antennas; 2 powerful radios and integration accessories. Piksi Multi features multiple high-density I/O connectors, providing an enhanced and improved integration experience.
Breakthrough Price
Swift Navigation is built on the notion that highly-precise RTK solutions should be offered at an affordable price. Piksi Multi embraces the foundation of unmatched affordability and is available at a much lower cost than comparable systems.

1 Hardware-ready for BeiDou B1/B2, Galileo E1/E5b, QZSS L1/L2. Piksi Multi GNSS Module has the RF front end to receive these signals but there are no precise implementation dates for future satellite systems.
2 SBAS Support includes the United States-based Wide Area Augmentation Systems (WAAS), the pan-European Union-based European Geostationary Navigation Overlay Navigation System (EGNOS), the Japanese Multifunctional Transport Satellites (MTSAT) Satellite Augmentation System (MSAS) providing coverage for Japan and Australia and the GPS-Aided GEO Augmented Navigation (GAGAN) regional system operated by the Indian government.
3 Current FW supports 10Hz GPS L1/L2C + GLN G1/G2 (low latency) or 5 Hz GPS L1/L2C + GLN G1/G2 (time matched).
4 As required by the U.S. Department of Commerce to comply with export licensing restrictions.
5 Typical power consumption by module in L1/L2 RTK positioning mode.
6 The CAN implementation Bus on Piksi Multi is currently hardware ready and is electrically verified. We do not support any specific CAN output protocol (eg. J1939) and have no immediate plans to do so. To help customers design specific CAN protocols, we have plans to release open Linux documentation to help integrators implement their own CAN messages.
7 A hardware update on the Piksi Multi to use a higher grade CPU with better thermal characteristics was implemented, resulting in 0.4mm height increase of the Piksi Multi. Contact customer support for more information on this.
8 The use of an on-board heat sink may be required only in some rare cases. The module ships with a provided heat sink attachment.
9 In open sky and strong signals conditions.
10 Hot Start is the time taken by the receiver to achieve a standard position fix after a brief outage. For example, the time taken to fix a position for a car that is exiting a long tunnel. This can also be simulated by a simple RF on/off test with outages between 30 and 50 seconds.
11 Cold Start is the time taken by the receiver to achieve a standard position fix after a prolonged outage. For example, the time taken to achieve a position fix for a car that has been parked overnight in a garage and once it sees the sky view for the first time.
12 Re-acquisiton is defined as the time taken to re-acquire position lock after brief moment of outage. For example, a car traveling under a freeway/highway overpass. This can also be simulated by a simple RF on/off test with outages between 1 and 5 seconds.
