Aircraft Navigation and Landing Guidance System

It can be used as a system that helps aircraft use GNSS to find the destination and airport when in flight and receive correction data from the DGNSS Reference Station near or inside the airport as they approach the airport. As such, they use the DGNSS navigation system to land accurately in the middle of the runway.

Very Accurate 3D Navigation Data Display in Light Aircraft

Today's light aircraft have control rooms, and the instrument landing system is typically integrated with dials, instruments, and indicators.In the past, stylish and expensive cockpit displays could be found in corporate and commercial airplanes. If the pilot of a light aircraft is not prepared with the route, he/she will experience difficulties in identifying the location of the required route as well as the navigation method to the destination. The standard of commercial airplanes, such as situational awareness, is important during approach, landing, and other phases of the flight. Very accurate, available, and motivated by a user-friendly control room display; aeronautical researchers at Stanford University also used DGNSS technology to build a glass control room machine that allows pilots to see the horizon, runways, and flight routes even in cloudy conditions or when visibility is low.Depicted on an activated-matrix liquid-crystal display like an icon, airways are indicated as a series of gray polygons while airplanes are indicated as small yellow triangles. The pilot can safely navigate the airplane along the intended route through the guidance of the yellow virtual airplane made of polygons. The system also shows altitude, direction, speed of air, and horizontal and vertical guide. The coordination simulation test and indoor flight demonstration show dramatic advantages beyond the traditional display.

Measuring Changes in the Atmosphere According to the Climate

Researchers at international marine atmosphere organizations use DGNSS technology to measure tremendous changes that occur in the ocean, land and biosphere to secure better accuracy and minimize costs. When measuring the movement of air at 5 cm/s on an airplane flying at a speed that is 1000 times faster, the research team deals with Trimble’s TANS Vector system and other DGNSS technology. This is because the TANS Vector's four-antenna system not only measures location, speed, and time but also pitch, roll, and azimuth of the object.

By observing inertia, researchers boosted the accurate altitude data collection capability of TANS Vector's 10 HZ to 50 times per second.
