Swift Navigation, a San Francisco-based tech startup building centimeter-accurate GPS technology to power a world of autonomous vehicles, released the second major firmware upgrade to its flagship product Piksi Multi GNSS module. The upgrade is available at no cost to Piksi Multi users and provides initial support for a new constellation (GLONASS), as well as increased functionality and improved performance. Firmware version 1.2 updates include: GLONASS Support - The new firmware provides dual frequency (L1/L2) GLONASS raw measurements for use cases such as post-processed kinematic (PPK) and custom navigation engines. Additionally, initial GLONASS navigation outputs expand receiver capability for Single Point Positioning (SPP). Further GLONASS navigation performance improvements are planned for future firmware releases. Fundamentally Improved RTK Float Solution - Piksi Multi’s float RTK output has been tuned to optimize the solution for autonomous machines and precision navigation. There is a step-change improvement of positioning performance in float mode. In fact, new and improved float solution performance can often fulfill precision navigation requirements. RTK Robustness - Swift has added a Measurement Integrity Assurance (MIA) feature that ensures only top quality pseudorange and carrier phase range measurements are used for navigation. This will improve navigation performance in the face of poor measurement conditions from multipath, pitch and roll of the antenna on dynamic vehicles, and temporary obstructions. Fundamentally Improved SPP Solution - Improving on its original ”single epoch” SPP, version 1.2 firmware has an advanced SPP solution that brings Swift’s estimation and filtering expertise to bear on the Single Point Position output when there are no RTK corrections. Version 1.2 also harmonizes the SPP output with Swift’s Differential Positioning output. Improved I/O Capabilities - This release continues to improve upon input/output (I/O) capabilities in the Piksi Multi receiver. Two fully configurable TCP/IP clients have been added, which, when coupled with the TCP/IP server features from prior releases, allow users to send and receive Swift Binary Protocol (SBP) information including RTK corrections across any LAN through settings changes only. The release also allows modification of the numerical TCP/IP server ports for compatibility with legacy systems. Version 1.2 also has improved stability of the micro-USB serial interface through a key bug fix to this interface. The addition of a Linux serial console and network adapter over the micro-USB interface allows advanced receiver command and control for developers. “The 1.2 firmware release marks a new era of performance for the Piksi Multi/Duro product lines,” said Anthony Cole, Ph.D., lead estimation engineer at Swift Navigation. “We have added GLONASS support for positioning and GLONASS raw observation output for PPK use cases, which makes the Piksi Multi/Duro product lines feature complete for a wide variety of applications.” “The addition of GLONASS support for positioning provides huge performance benefits in challenging environments, including urban environments and under foliage,” Cole added, ”This release highlights Swift Navigation’s ability to develop new features for the Piksi Multi/Duro product lines with unparalleled speed; due to our unique hardware architecture and innovative approach to testing, we have shipped GLONASS support a mere 5 months after the previous firmware release, with no changes to the Piksi Multi hardware required.” For more detailed information about these upgrades, please refer to the Piksi Multi Firmware 1.2 Release.
