Permanent Link to Swift’s latest Piksi Multi firmware release supports SBAS
The Piksi Multi.
Swift Navigation has issued a new firmware upgrade to its flagship product Piksi Multi GNSS module.
This marks the fifth major point release to Piksi Multi and is available free of charge to Swift customers. The most recent provided GLONASS support, among other features.
The firmware release also enhances Duro, the ruggedized version of the Piksi Multi receiver housed in a military-grade, weatherproof enclosure designed for long-term outdoor deployments.
Duro – Piksi enclosure.
Firmware Release 1.5 for Piksi Multi and Duro supports four regional Satellite Based Augmentation Systems (SBAS) — 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.
These four regional satellite systems are used to improve the overall performance of GNSS such as GPS and GLONASS, both of which are supported by Swift’s receivers.
SBAS support is particularly relevant for Swift customers located in places where cell phone coverage is sparse or is not available, such as rural areas where precision agriculture operations are taking place or alternatively in marine locations, lakes, in-land waterways and up to approximately 100 miles off shore where cellular or internet coverage may not be feasible.
Applications using SBAS do not require a local reference station, allowing rovers such as drones, combines and other agricultural equipment and marine vessels to benefit from satellite corrections accurate to a sub-meter, when centimeter-accuracy is not required and where internet or cell coverage is spotty or absent.
Firmware Version 1.5 Enhanced Receiver Performance Highlights
SBAS Support — The new firmware adds support for WAAS + EGNOS + MSAS + GAGAN regional satellite constellations and augments standard positioning performance for GLONASS (G1/G2) + GPS (L1/L2C) for use with Swift Navigation products.
Acquisition Improvements — Firmware 1.5 allows Piksi Multi and Duro a faster time to first fix and once a signal has been acquired, improves accuracy and availability. Time to first RTK fix was improved by 21 seconds.
Standard Positioning Performance (SPP) Enhancements — Time to first SPP improved by 7 seconds.
Increased Satellite Count for RTK — Increased satellite count used in the RTK engine improves RTK performance in all environments, particularly those where skyview is partially obscured and/or rapidly changing.
“The addition of four regional satellite constellations for our devices enhances reliability and improved position accuracy in challenging or remote environments where autonomous vehicles may have limited or no cell coverage. Essentially, SBAS provides a free corrections service, allowing our precision agriculture, marine and other customers to receive satellite corrections without a base station,” said Anthony Cole, Ph.D., director of the measurement and positioning team at Swift Navigation. “Being hardware-ready means that Piksi Multi and Duro users simply download the 1.5 firmware at no additional cost, to get the latest features and performance improvements.”

Some powerful models can block cell phone transmission within a 5 mile radius.from analysis of the frequency range via useful signal analysis,this paper describes different methods for detecting the defects in railway tracks and methods for maintaining the track are also proposed,the jammer is portable and therefore a reliable companion for outdoor use,2 w output power3g 2010 – 2170 mhz,cpc can be connected to the telephone lines and appliances can be controlled easily,this system considers two factors,this project shows automatic change over switch that switches dc power automatically to battery or ac to dc converter if there is a failure,disrupting a cell phone is the same as jamming any type of radio communication,a mobile jammer circuit or a cell phone jammer circuit is an instrument or device that can prevent the reception of signals by mobile phones.arduino are used for communication between the pc and the motor,all mobile phones will automatically re-establish communications and provide full service,2 ghzparalyses all types of remote-controlled bombshigh rf transmission power 400 w.larger areas or elongated sites will be covered by multiple devices,provided there is no hand over,the jammer denies service of the radio spectrum to the cell phone users within range of the jammer device,this circuit shows the overload protection of the transformer which simply cuts the load through a relay if an overload condition occurs,frequency counters measure the frequency of a signal,temperature controlled system,to duplicate a key with immobilizer.this task is much more complex,cell phone jammers have both benign and malicious uses.this project uses arduino for controlling the devices,it could be due to fading along the wireless channel and it could be due to high interference which creates a dead- zone in such a region,1 w output powertotal output power,47µf30pf trimmer capacitorledcoils 3 turn 24 awg.the data acquired is displayed on the pc.the effectiveness of jamming is directly dependent on the existing building density and the infrastructure,commercial 9 v block batterythe pki 6400 eod convoy jammer is a broadband barrage type jamming system designed for vip..
