Saudi Group Awards Water Resources Prize to GNSS Researchers

The GPS Reflections Group at the University of Colorado, Boulder, led by Dr. Kristine M. Larson, has received the Creativity Prize from the Council for the Prince Sultan Bin Abdulaziz International Prize for Water.

The council awarded the prize today (December 15, 2014) at a ceremony preceding the 6th International Conference on Water Resources and Arid Environments (ICWRAE 6) taking place this week in Riyadh, Saudi Arabia.

2nd GLONASS-K1 Finally Reaches Space

GLONASS-K1 at ISS-Reshetnev

Russia launched the second and final GLONASS-K1 flight-test satellite on Sunday (November 30, 2014) from the Plesetsk cosmodrome on board a Soyuz 2-1B rocket.

Built by ISS-Reshetnev, the satellite broadcasts five navigation signals in three frequency bands – L1, L2 and L3. A civil CDMA signal is among those to be transmitted in the L3 band. The spacecraft also carries new equipment to support the international search and rescue system COSPAS-SARSAT: a payload that can relay signals from users in distress.

Precise Positioning Techniques

Everyone talks about GNSS precision and accuracy, but how do we get it?

On Monday, December 15, three experts in the field discussed the leading high-accuracy GNSS techniques of real-time kinematic (RTK) and precise point positioning at a free, 90-minute webinar. You may still register to view the recorded version.

New Technology Could Enable UAVs to Fly Vertically

UT-Corpus Christi students Ian Gates (left) and Christoph Hintz review the characteristics of the 3-dimensional computer-aided design prototype. The experimental prototype should look and work like the 3D model.

Imagine an unmanned multi-copter that doesn’t just fly horizontally, but that has the capability to fly vertically as well.

This UAV would have the ability to transition from the horizontal orientation most rotor drones fly in, and rotate its body to a vertical orientation, offering access to tight and irregular spaces conventional drones just can’t reach—a capability that could drastically improve search and rescue efforts in collapsed buildings.

Using Unmanned Systems to Fight Wildfires

Large wildfires can create their own weather and a dynamic, uncertain environment, and that is one of the reasons they’re so dangerous, says Manish Kumar, an Associate Professor in the Department of Mechanical, Industrial, and Manufacturing Engineering at the University of Toledo.

Unmanned Exemptions Requests Pile Up, NTSB Backs Commercial UAS Restrictions

The number of special requests to fly unmanned aircraft commercially has surpassed 130 as firms search for a way around a federal ban on for-pay flights. The new numbers came to light the same day a court decision underscored regulators’ authority to rein in the industry with restrictions unlikely to be lifted until new rules are put in place years from now.

Europe Prepares Its Part of GNSS-Enhanced Search & Rescue Service

Cospas–Sarsat’s extension to MEOSAR (Medium Earth Orbit Search and Rescue) will extend its search and rescue coverage (the area outlined in red). On the ground the Galileo programme is contributing a Toulouse-based test bench, and a networked trio of MEOSAR ground stations – known as Local User Terminals (LUTs) – to cover Europe, based in Svalbard in the Norwegian Arctic, Cyprus and the Canary Islands. Existing LUTs are distributed on a per country basis, but it is an advantage of MEOSAR that fewer ground stations will be needed for greater coverage. Cospas-Sarsat illustration

The European Space Agency (ESA) has announced completion of tests that indicate the readiness of the European component of a modernized, GNSS satellite–aided search and rescue service known as Cospas-Sarsat.

ESA has completed construction and testing of a trio of located on three islands at the far corners of the continent, ready to pick up distress calls via satellite from across Europe and its surrounding waters.

Reliable GPS-Based Timing for Power Systems

Efficient power transmission and distribution would benefit from synchronized near–real-time measurements of voltage and current phasors at widely dispersed locations in an electric power grid. Such measurements also could enable effective real-time system monitoring and control, which are considered to be the key to preventing wide-scale cascading outages like the 2003 Northeast Blackout.

What are the actual performances of GNSS positioning using smartphone technology?

Tables 1, 2, 3 & 4

Q: What are the actual performances of GNSS positioning using smartphone technology?

A: “Where I am?” is the typical question asked by a person when visiting a new city or unknown place. Knowing one’s own location is generally a basic necessity for people, both in indoors and outdoors.

Multi-GNSS Precise Positioning

Dennis Odijk, Curtin University

The availability of carrier phase tracking — counting the cycles of GNSS signals between satellites and a receiver — has long enabled high-precision users to achieve greater accuracy than using the navigation messages or pseudoranges. Improvements in high-end receivers and techniques such as real-time kinematic (RTK) and precise point positioning (PPP) have made once inconceivably accurate results almost routinely accessible.
