Vector H200 processes L1 GPS and GLONASS signals to deliver precise heading, greater positioning reliability, and better performance in challenging environments, Hemisphere GNSS said. Through using two separate antennas, Hemisphere GNSS’ patented Vector technology computes the heading and pitch or roll angle while stationary or in motion. Vector H200 can compute heading accuracy to 0.02 degrees using a 5-meter antenna separation. A variety of differential correction methods also make it possible for Vector H200 to provide sub-meter to centimeter position accuracy.

Marine industry developers can maximize performance by integrating Vector H200 into their systems for hydrographic and bathymetric surveys, auto-pilots, dredging, and buoys. For land applications, Vector H200 is ideal for aligning cameras, antennas and projectiles, and for machine control applications in agriculture, construction, and mining.

“System integrators have a lot to gain from Vector H200’s powerful combination of navigation and machine control orientation capabilities,” said Ron Ramsaran, Sr. Product Marketing Manager at Hemisphere GNSS. “They will appreciate the performance and value from such a small board package.”

Vector H200 supports SBAS, L-Band and RTK differential positioning solutions and features our exclusive SureTrack technology optimizing the use of GPS and GLONASS signals. Hemisphere GNSS offers precise GNSS antennas to fit a variety of Vector H200 applications.

According to the article, “The recently completed phase at DIA trims arrival and departure fuel costs by eliminating several intermediary steps. The traditional system requires an airplane to come into and out of cruising altitude by firing its thrusters at every new altitude level, wasting hundreds of pounds of fuel… The traveling public will not likely notice an immediate difference in travel time, but proponents hope that the early investment pays off in the end.”

The FAA predicts that NextGen improvements will reduce flight delays by 38 percent and lead to a 1.4-billion-gallon total reduction of fuel burn by 2020.

The NexNav Circuit Card Assembly (CCA) will integrate with FreeFlight’s upgraded automatic dependent surveillance-broadcast (ADS-B) avionics to fulfill the requirements of the second phase of the FAA Capstone Project.

“This is an excellent example of how we are working closely with FreeFlight Systems to create state-of-the-art NextGen solutions that are not only meeting upcoming mandate requirements but doing it in a cost effective manner,” stated Hal Adams, Chief Operating Officer for Accord Technology, LLC.

The Accord Technology NexNav product line revolves around two key receivers, NexNav mini and NexNav MAX. The receivers are at the heart of embedded customer solutions whether as a Circuit Card Assembly (CCA) or embedded in the Line Replacement Unit (LRU) as a stand-alone GPS solution.

NexNav mini was the industry’s first GPS receiver and sensor qualified to fully support the known worldwide and U.S. FAA ADS-B GPS source requirements The NexNav mini and MAX are compatible with EGNOS and other Satellite Based Augmentation Systems (SBAS) to the extent they are is compatible with WAAS.

In 2011 the European GNSS Agency (GSA) awarded GMV the EEGS2 project (EGNOS Extension to Eastern Europe). The main objective of the project is to demonstrate through flight trials the benefits of the European Geostationary Navigation Overlay Service (EGNOS) in areas of Eastern Europe where it is not yet available, such as Poland, Romania, Ukraine, Moldova and Russia, and to prepare the civil aviation authorities and air navigation service providers for future use of the system.

GMV’s magicSBAS solution.

In the context of this project, after the tests conducted in Spain, the maiden flights have been successfully carried out in Moldova, using the equipment and tools developed by GMV. The Moldova demonstrations have given pilots and service providers a clear idea of the potential benefits of EGNOS and the flying procedures of the near future, GMV said.

Four flights had previously been conducted in Spain in November, December and February. The satisfactory results of these flights then paved the way for the demonstrations in Moldova.

The magicLPV system, developed under this project, enables LPV approaches (localizer performance with vertical guidance) to be carried out using the signal generated by the magicSBAS application. This test environment allows any region of the world to analyze the air-navigation benefits to be obtained with deployment of a Space Based Augmentation System (SBAS). This signal is read by Internet and transmitted by radio frequency in the vicinity of the airport, allowing LPV approaches to be made in places where SBAS is either completely unavailable or available only on a very limited basis.

Eight flights in all were carried out in various Moldovan airports, including Chișinău International Airport. Test results were highly satisfactory, demonstrating the simplicity of equipment configuration and operation, and the performance of the magicSBAS signal, GMV said.

“These trials are an important milestone for GMV, for the project and, fundamentally, for the use of EGNOS in the countries of Eastern Europe in the near future,” said Miguel Romay, executive director of GNSS–Aerospace.

GMV will continue with these demonstrations in other countries of Eastern Europe. The next trip in two weeks will be to Romania, where new flights are expected to be just as successful.

“The Houston Airports are among the most innovative and progressive in the nation when it comes to safety and efficiently connecting passengers to destinations around the world,” said Mario Diaz, director of the Houston Airports. “It is imperative that we continue to invest in new technology that enhances the aviation sector.”

Honeywell’s SmartPath GBAS system augments GPS signals so they can be used for precision navigation in the approach and landing phases of flight. The flexible approaches provided by GBAS may produce a significant reduction in aircraft delays and carbon emissions at airports. The project is a component of the Federal Aviation Administration (FAA) Next Generation Air Transportation System (NextGen). It’s a migration from what is considered to be a ground-based air navigation system to a satellite-based navigation system which uses the same GPS that you use in your cars today.

“There is a great opportunity for SmartPath to modernize the flight experience for airline passengers,” said Pat Reines, senior manager, SmartPath Ground Based Augmentation Systems at Honeywell Aerospace. “We’re looking forward to helping Houston passengers and visitors’ experience more flights that depart and arrive on time.”

United Airlines will operate the flights with a Boeing 737 aircraft equipped with global navigation satellite system (GNSS) landing system (GLS) technology to receive the GBAS landing approach data. United was an early leader in NextGen technology, taking delivery of GLS-equipped aircraft since 2009.

“We believe that GBAS is the air carrier precision landing system of the future,” said Captain Joe Burns, United’s managing director of technology and flight test. “We continue to work closely with the FAA and our industry partners on GBAS and other NextGen initiatives.”

GBAS can provide aircraft with guidance to as low as 200 feet above the surface of the runway, referred to as a Category I approach. The FAA is currently validating the requirements for a GBAS to support Category II and Category III precision approach operations which would guide an aircraft to the surface of the runway. GBAS represents the only currently feasible satellite-based navigation solution for Category II/III precision approach operations, according to the Houston Airport System.

“We really appreciate the professional and amicable cooperation with Applanix, which allows us to offer user-friendly and powerful, fully integrated solutions for dynamic data acquisition to the marketplace,” said Jürgen Nussbaum, Riegl director of international sales.

In addition, Applanix will be a Gold sponsor at Riegl LIDAR 2013, Riegl’s international user conference taking place in Vienna, Austria, June 25-27.

Aeroflex has developed the capability of simulating WAAS LPV approaches to expedite and validate the installation of WAAS-enabled navigation systems in aircraft. The GPSG-1000 offers the following features to installers of these systems:

• Ability to perform structured, repeatable dynamic motion tests (actual flight) of a WAAS/LPV installation,
• Ability to check and validate the sensitivity and dynamic range of an airborne GPS receiver, either statically or while in motion,
• Reduce aircraft down time and flight demonstration time required by FAA,
• Additional support data for documenting proper FAA processes of WAAS/LPV system upgrades or installs without leaving the hangar.

New orders for the GPSG-1000 are ready for immediate delivery. For existing GPSG-1000 customers, a no-charge software upgrade will be available by mid-April 2013.

The FAA created the WAAS program in 1992 to provide the necessary integrity to utilize GPS signals for precision approach. The WAAS consists of a network of precisely surveyed wide area reference stations (WRS). These reference stations monitor GPS satellites to determine errors in the GPS satellite signal. Each reference station relays the information about the GPS satellites to the WAAS wide area master stations (WMS). The master station then develops corrections to the GPS position information and provides timely notification of unreliable GPS data. These corrections are sent to ground uplink stations (GUS) where they are transmitted in the form of a WAAS correction message to a Geostationary Earth Orbit (GEO) satellite. The WAAS signal is then broadcast to users on the same frequency as GPS. This WAAS corrected signal provides three-dimensional guidance to aircraft.

The test receiver. The helicopter flew a variety of maneuvers, from fast loops to mid-air hovering, to see how satnav signals were received in practice.

Results of the flight test, conducted in September 2012, show that adding Galileo signals to the European Geostationary Navigation Overlay Service (EGNOS) should boost its accuracy significantly. EGNOS, which augments the accuracy and reliability of GPS signals over Europe, renders satnav usable for safety-critical applications such as aircraft guidance, as well as more general precision uses.

Operational horizontal and vertical distance “protection levels” for safety were cut by half by combining use of GPS and Galileo within EGNOS. In addition, new integrity algorithms installed within the user receiver turned out to reliably detect and exclude reflected or otherwise faulty signals.

The first test of real Galileo navigation fixes is scheduled for later this year from the four satellites already in orbit, with more satellites set to join them by the end of the year.

The Galileo Test and Development Environment – GATE – is a giant outdoor laboratory where prototype Galileo receivers can be used freely without any modifications.

As the constellation takes shape, satnav researchers and industrial developers can already try out Galileo services with prototype receivers at the German Galileo Test and Development Environment, or GATE, a giant outdoor laboratory. GATE, in and around the town of Berchtesgaden in the Bavarian Alps, is Europe’s go-to place for Galileo testing: transmitters atop eight neighbouring mountains cover 65 square kilometers of territory with simulated Galileo signals.

ESA’s Global Navigation Satellite System Evolution program carried out helicopter-based testing here on September 24–26. The results will help to guide the development of next-generation satnav systems.

The helicopter flew a variety of maneuvers, from fast loops to mid-air hovering, to see how satnav signals were received in practice. The test relied on ESA’s SPEED platform — Support Platform for EGNOS Evolutions & Demonstrations, co-funded by French space agency CNES and operated by Thales Alenia Space France — which enabled the receiver to receive simultaneous realtime augmentation for both GPS and Galileo.

Europe’s next-generation EGNOS, planned for around 2020, is envisaged to operate in the same way, with augmentation of both constellations and dual-frequencies at the same time making the system much more robust.
