    A G4 (severe) geomagnetic storm is now taking place, the most powerful solar storm of the current solar cycle, reports Discovery.com.

    Initially triggered by the impact of a coronal mass ejection (CME) hitting our planet’s magnetosphere, a relatively mild geomagnetic storm erupted at around 04:30 UT (12:30 a.m. EDT), but it has since become a severe G4-class geomagnetic storm. Bright auroras were sighted over several northern-tier U.S. states including Minnesota, Wisconsin, Montana, the Dakotas and Washington. The storm could continue for many hours as Earth passes through the turbulent wake of the CME.

    Storm conditions are forecast to persist for the next several hours before beginning to wane down towards the end of the UT day.

    Not all types of solar activity (sun spots, solar flares, solar burst, and solar radiation) affect GPS receiver operations. Geomagnetic storms, however, can cause problems for GPS receivers if the storms are powerful enough.

    The solar cycle is about 11 years long, during which the sun waxes and wanes in magnetic activity.

    By the European Space Agency

    The sixth Galileo satellite of Europe’s navigation system has entered its corrected target orbit, which will allow detailed testing to assess the performance of its navigation payload.

    Launched with the fifth Galileo last August, its initial elongated orbit saw it traveling as high as 25,900 km above Earth and down to a low point of 13,713 km — confusing the Earth sensor used to point its navigation antennas at the ground.

    A recovery plan was devised between ESA’s Galileo team, flight dynamics specialists at ESA’s ESOC operations centre and France’s CNES space agency, as well as satellite operator SpaceOpal and manufacturer OHB. This involved gradually raising the lowest point of the satellites’ orbits more than 3500 km while also making them more circular.

    The fifth Galileo entered its corrected orbit at the end of November 2014. Both its navigation and search and rescue payloads were switched on the following month to begin testing. Now the sixth satellite has reached the same orbit, too.

    This latest salvage operation began in mid-January and concluded six weeks later, with 14 maneuvers performed in total. Its corrected position is effectively a mirror image of the fifth satellite’s, placing the pair on opposite sides of the planet. The exposure of the two to the harmful Van Allen Belt radiation has been greatly reduced, helping to ensure future reliability.

    Significantly, the corrected orbit means they will overfly the same location on the ground every 20 days. This compares with a standard Galileo repeat pattern of every 10 days, helping to synchronize their ground tracks with the rest of the constellation.

    The test results from Galileo 5 proved positive, with the same test campaign for the sixth satellite due to begin shortly, overseen by ESA’s Redu centre in Belgium. A 20 m-diameter antenna will study the strength and shape of the navigation signals at high resolution.

    “I am very proud of what our teams at ESA and industry have achieved,” says Marco Falcone, head of Galileo system office. “Our intention was to recover this mission from the very early days after the wrong orbit injection. This is what we are made for at ESA.”

    The decision whether to use the two satellites for navigation and search-and-rescue purposes will be ultimately taken by the European Commission, as the system owner, based on the in-orbit test results and the system’s ability to provide navigation data from the improved orbits.

    The next pair of satellites is due for launch on March 27.

    Trimble announced today a new version of its CenterPoint RTX correction service that delivers convergence to 4-centimeter horizontal accuracy in less than 5 minutes. The service is designed for a variety of precision agriculture operations in Central and Western Europe, and is available for use with the Trimble CFX-750 display.

    Trimble CenterPoint RTX delivers highly accurate GNSS corrections via satellite without the need for traditional reference station RTK infrastructure, mobile data plans or additional on-machine hardware. The GNSS-enabled correction service delivers repeatable, real-time high-accuracy positions for land preparation, planting, harvesting and other high-precision farming applications.

    Enabled by the new version of RTX technology, RTX version 5.0, the fast convergence time is the result of a new region-specific atmospheric model and a dense ground reference station network. Growers will realize an approximate 80 percent improvement in RTX convergence time as compared to the RTX-standard service that typically provides 30-minute convergence time, Trimble said.

    Delivered via a new satellite broadcast covering western and central Europe, the new service will be available in Austria, Belgium, Czech Republic, France,Ireland, Germany, Luxembourg, the Netherlands, Western Poland, Southern Sweden and the United Kingdom.

    “We are continually advancing our Trimble RTX technology to improve productivity in the field,” said Patricia Boothe, general manager of Trimble Positioning Services. “Faster initialization times allow growers to start working more quickly, freeing up time to focus on other farm operations. No other satellite-delivered correction service today can offer better than 4 centimeter accuracy in less than 5 minutes.”

  • Launch Prep on Track for Galileo’s Next FOC Satellites

    Launch Prep on Track for Galileo’s Next FOC Satellites

    Preparations for Arianespace’s next Soyuz flight, which will lift into orbit two more Galileo satellites, are in full swing at multiple locations across the spaceport in French Guiana. Work includes a key integration step for the medium-lift launcher, plus the start-up of fueling for its Galileo satellite passengers.

    Soyuz’ Block I third stage was mated to the vehicle’s core during activity today in the MIK Launcher Integration Building, concluding its basic build-up. Once the checkout process is completed, Soyuz will be transferred to the launch pad, where it will receive the two Galileo spacecraft and the Fregat upper stage, all of which are well into preparation phases of their own.

    Payload fueling began earlier this week, with Galileo 8 (Galileo FOC-FM4) — the fourth Galileo Full Operational Capability (FOC) satellite, and eighth overall — receiving its propellant load in the Spaceport’s S5A fueling and integration hall. After its sister Galileo FOC-FM3 (Galileo 7) co-passenger undergoes this same process, the two will be integrated side-by-side on a dispenser for their shared ride aboard Soyuz on March 27.

    The fueling process followed the finalization last week of FM3 and FM4’s hardware and software, as well as the charging of their batteries — which will be relied upon during the short period from launch to unfurling of these spacecraft’s solar arrays in orbit.

    The Galileo program is Europe’s initiative for satellite navigation, providing a highly accurate global positioning system under civilian control — to consist of 30 satellites in total, along with European control centers and a worldwide network of sensor and uplink stations.

    Galileo’s FOC phase — during which the network’s complete operational and ground infrastructure will be deployed — is managed and funded by the European Commission, with the European Space Agency delegated as the design and procurement agent on the Commission’s behalf.

    The FM3 and FM4 spacecraft were built by OHB System in Bremen, Germany. Their navigation payloads, which will generate the precision positioning measurements and services to users worldwide, were supplied by Surrey Satellite Technology Ltd. in Guildford, UK.

    This upcoming mission is designated Flight VS11 in Arianespace’s numbering system. It will be the company’s fourth launch carrying spacecraft for the Galileo constellation, as well as the 11th flight of a workhorse Soyuz from French Guiana since the 2011 introduction.

  • PPP Solution from NovAtel Improved for Sub-Decimeter Accuracy

    NovAtel has announced significant performance improvements to its precise point positioning (PPP) solution. NovAtel CORRECT with PPP will now offer the new TerraStar-C correction service as its exclusive source for satellite-delivered PPP correction data.

    TerraStar-C contains an enhanced correction data set that enables up to 4-centimeter accuracy and instant re-convergence when combined with the receiver error models and positioning algorithms offered by NovAtel CORRECT. This new level of PPP performance is available on NovAtel’s OEM6 receivers with firmware version 6.600.

    NovAtel CORRECT is the positioning algorithm on NovAtel’s GNSS receivers that handles corrections from a variety of sources, including real-time kinematic (RTK), PPP, spaced-based augmentation systems (SBAS) and differential GPS (DGPS). NovAtel CORRECT with PPP combines GNSS satellite clock and orbit correction data from TerraStar’s global reference station network with NovAtel’s receiver algorithms to yield robust sub-decimeter positioning without the need for nearby base stations.

    Correction data provided by TerraStar is delivered to the end user via Inmarsat satellites. With satellites visible globally, PPP is an ideal solution for precision applications where communications infrastructure is either unreliable or not available. In addition, applications where signal interruptions are common will benefit from a more robust positioning solution with the ability to quickly regain full accuracy following a temporary loss of GNSS signals, NovAtel said.

    NovAtel customers with current TerraStar-D subscriptions have the option to upgrade to the new TerraStar-C service level free of charge. The new NovAtel PPP performance level is available immediately.

  • Orbit of Second Wayward Galileo Satellite Adjusted

    Editor’s Note: See the report from the European Space Agency here.


    An official with the European Space Agency has confirmed that the sequence of maneuvers to adjust the orbit of the second of two Galileo satellites launched into a wrong orbit in August 2014  has been completed.

    The orbit of the first satellite, known variously as GSAT0201, Galileo FOC-FM1 or Galileo 5 (with COSPAR ID 2014-050A and NORAD ID 40128) was raised during operations carried out in November, and the satellite began transmitting L-band signals on Nov. 29.

    Maneuvering of the second satellite (GSAT0202, Galileo FOC-FM2 or Galileo 6, with COSPAR ID 2014-050B and NORAD ID 40129) began around Jan. 15. The procedure took somewhat longer than that for the first satellite as it also involved changing the mean anomaly of the satellite to be about 180° away from that of the first satellite.

    The locations of the satellites in the Galileo constellation are shown in the accompanying figure. Satellites in green are transmitting a full complement of L-band signals. Galileo 4 (GSAT0104), one of the in-orbit validation satellites, suffered a power anomaly and only transmits on the E1 frequency. Galileo 5 is transmitting L-band signals but its orbit cannot be properly represented in the Galileo broadcast almanac. Galileo 6 has not started transmitting valid L-band signals yet.

    Officially, all Galileo signals are currently declared unavailable during an extended period of testing following ground segment upgrades. However, signals continue to be monitored by stations participating in the International GNSS Service Multi-GNSS Experiment.
