Hemisphere GNSS Vector Products Now Have GLONASS Functionality

March 11, 2014By

Hemisphere GNSS has announced that all professional-level Vector products — including the V103, V113, VS131, and VS330 — now include the ability to utilize the GLONASS system along with GPS in the navigation solution. The tracking of the additional GLONASS signals provides a more robust solution, especially in challenging environments, the company said. Vector Technology processes L1 GPS and GLONASS... read more

Comment Period on Pre-Operational CNAV Message Opens

March 5, 2014By
Carrier-to-noise ratio of L5 signals, measured on June 19, 2013, by  Zheng Yao and colleagues at Tsinghua University, China. Signals were analyzed from three GPS satellites whose PRN numbers are 1, 24, 25, and one QZSS satellites with the PRN of 193 at time of acquisition.

A Federal Register Notice has been published allowing for a 30-day comment period on the proposed CNAV message on L2C and L5. The notice seeks comment from the public and industry regarding plans by the U.S. Air Force to broadcast pre-operational L2C and L5 civil  navigation (CNAV) messages from certain GPS satellites beginning in April. The Department of Transportation is... read more

The System: Galileo Accomplishes In-Orbit Validation

March 1, 2014By

Galileo Accomplishes In-Orbit Validation Nucleus of Four Now Operational: It “Works, and Works Well” The European Space Agency (ESA) announced fulfillment of the in-orbit validation (IOV) of Galileo on February 10. IOV was achieved with four satellites, the minimum number needed to perform navigation fixes. “IOV was required to demonstrate that the future performance that we want to meet when... read more

SBAS Working Group Looks to Galileo for Aircraft Guidance, Defines L5

February 28, 2014By
Planned GAGAN service coverage for the two different service levels (RNP0.1 and APV1). GAGAN has been jointly undertaken by the Airport Authority of India and the Indian Space Research Organization, ISRO, to achieve smooth transition to satellite-based navigation and seamless air traffic management across continents. GAGAN is designed to provide improved accuracy, availability and integrity necessary to enable users to rely on GPS for all phases of flight, from en route through approach for all qualified airports within the GAGAN service volume. More precisely it is aimed to provide Non Precision Approach RNP0.1 service levels to the entire Indian Flight Information Region and Precision Approach APV1 service (equivalent to the current EGNOS Service) within a specified service volume within Indian land mass.

Plans to harness Galileo and other satnav systems for next-generation satellite augmentation systems for aviation and other high-performance uses took a significant step forward at the latest gathering of worldwide operators and experts, reports the European Space Agency. Satellite augmentation systems combine additional ground stations and satellite transponders to sharpen satnav accuracy and reliability across given geographical regions — based... read more

The hounds of spring are on winter’s traces. As Galileo emerges from its long, cold slumber, the energy of a new constellation radiates through the skies to encourage blossoms across Europe. ESA’s recent declaration of in-orbit validation means the downstream satnav market can now truly get going. If a lot of demand has yet to be demonstrated, certainly a lot... read more

Imec and Septentrio have collaborated to design multi-frequency GNSS antenna that simultaneously receives all GPS, GLONASS, BeiDou, and Galileo bands. Developed under the European Community’s Seventh Framework Programme project Handheld, the compact antenna can be integrated in multi-frequency handheld GNSS devices for high-precision location applications up to 1 centimeter. The announcement came at the Mobile World Conference being held this week... read more

New GPS IIF Satellite Launched

February 21, 2014By
A United Launch Alliance Delta IV lifts off from Space Launch Complex-37 with the Air Force's Global Positioning System (GPS) IIF-5 satellite. This launch marked the 25th Delta IV flight since the first flight in 2002.

News compiled with the assistance of CANSPACE listserv. After a brief delay due to concerns over solar radiation trends, the GPS IIF-5 satellite was successfully launched at the end of the designated launch window at 01:59 UTC on February 21. The satellite, attached to the launch rocket’s upper stage, was initially placed in a highly elliptical orbit. Following a third... read more
