Global Positioning System in Aviation

The Global Positioning System (GPS) is on space-based radio-navigation system. It consists of a group of satellites broadcasting signals. It also includes a network of ground and satellite control stations used for monitoring and control. Aviation GPS (Global Positioning System) is the leading emergent aviation navigation type. ErgoBlue is the best aviation GPS app for iPad out of the many. This app helps display accurate plane positions and access airport directories.


Aviators worldwide use the aviation GPS (Global Positioning System) to increase the safety and efficiency of flight. With its accurate, continuous, and global capabilities, aviation GPS offers smooth satellite navigation services that satisfy many requirements for aviation users. Space-based position and navigation facilitate three-dimensional position determination for all phases of flight from departure, en route, and arrival, to airport surface navigation.

Aviation GPS allows aircraft to fly user-preferred routes from waypoint to waypoint, where waypoints do not depend on ground infrastructure. Cockpit view of pilots landing a plane, the trend towards an area navigation concept means a more significant role for aviation GPS. As a result, procedures have been expanded to use aviation GPS and enlarged services for all phases of flight. This has been especially true in areas that lack suitable ground-based navigation aids or surveillance equipment.

Both private jet aircraft and commercial airlines now use GPS to navigate. Aircrafts have been tracked by radar since World War II. Despite significant changes, radar is still relatively expensive and requires extensive infrastructures. Radar is also vulnerable to changing condition and physical obstacles. But with aviation GPS, a simple but accurate solution is already available and installed in every aircraft. New and more efficient air routes made possible by aviation GPS are expanding. As a result, vast savings in time and money are being realize. In many cases, aircraft flying over data-sparse areas such as oceans have been able to safely reduce their separation from one another and allow more aircraft to fly more favorable and efficient routes, saving time and fuel and increasing cargo revenue.

Aviation GPS has improved the approach to airports, which significantly increased operational benefits and safety. Aviation GPS is now being implemented even at remote locations where traditional ground-base services are unavailable. In some regions, satellite signals are improve for special aviation applications, such as landing planes during poor visibility conditions. In those cases, even greater precision operations are possible.


Aviation GPS is being constantly improve and modernize. A central component of the ongoing civilian transformation effort is the addition of two new signals. These signals complement the existing civilian service. The first of these new signals is for everyday use and will be internationally protect; the second new signal is for aviation GPS navigational purposes. This additional safety-of-life civilian signal will make aviation GPS even more active navigation service for many aviation applications. The second safety-of-life signal will empower significant assistances above and beyond the capabilities of the current aviation GPS services.

The availability of this signal offers increased instrument approach opportunities throughout the world. It is also able to make use of dual-frequency avionics possible. Dual-frequency means that errors that occur in the signals due to disturbances in the ionosphere can be significantly reduced by simultaneously using two signals. This will improve the overall system robustness, including accuracy, availability, and integrity. In addition, it will allow a precise approach capability with little or no ground infrastructure investment.

Dependence on aviation GPS is the foundation for today and tomorrow’s air traffic management system. Aviation GPS is a significant part of many national plans. Those aviation authorities moving forward with aviation GPS have perceived and recognized reductions in flight time, workload, and operating costs. Aviation GPS also aids as an essential constituent for many other aviation systems, such as the Enhanced Ground Proximity Warning System (EGPWS). EGPWS has successfully reduced the risk of Controlled Flight into Terrain, a significant cause of many aircraft accidents.


Aviation GPS has made the flight more efficient and safe in the following ways:

  •  It replaces the real-time VFR (Visual Flight Rules) navigation system, which tracks the plane position offline.
  • Aviation GPS accuracy and reliability have led some pilots to depart VFR on days when the visibility is too low for VFR navigation.
  •  VFR means seeing the landscape well enough to verify your position on a map.
  •  The VFR sees the landscape well enough to secure your work on map.
  •  Entering the wrong waypoint coordinates could have a pilot flying very accurately to the wrong   place.
  •  This could lead to the loss of control owing to disorientation or collision with unseen obstacles
  • It includes online Google Maps support.
  •  Good training with various types of aviations GPS is essential.
  •  Aviation GPS is the most accurate navigational system ever invent.
  • Aviations GPS is available free of charge without any subscription or license.
  • Unlimited users could take advantage of this system without any compromise on the quality of  the signal.
  • Aviations GPS could hit the target without causing significant collateral damages.


What if two aircraft on opposite paths are using aviations GPS? Does the risk of collision increase?

Aviations has come so far in the last 100 years that now we rely heavily on GPS (Global Positioning System) for navigation. ICAO (The International Civil Aviation Organization), Transport Canada, and NAV CANADA have been studying this for several years and have not come to a concrete conclusion. They rely on various procedures and services to avoid collisions.

  • Flying at an altitude appropriate to the direction of flight.
  • Using radar and position reports.
  • Communications (on the proper frequency) with other pilots in uncontrolled airspace and near airports without control or advisory service; and watching for other traffic.
  • Some have suggested flying offset tracks.
  • ATC (Air Traffic Control) provides the essential margin of safety.
  • For VFR, the question is: offset from what?
  • All we can suggests at this point is that pilots using GPS on regular VFR routes could stay to the    right of the center.
  • This recommend when flying along rivers or valleys.
  • It does not interchange communicating, watching for other traffic, and minimizing head-down time.


Before there was aviation GPS, the then pilots flew this way. These crazy pioneer pilots flew 200 to 400 feet AGL (Above Ground Level). They were relying on the use of only a magnetic compass, roads, and railways for navigation. During low visibility and night flights, the authorities used bonfires to light up the way. They still do that for airstrips in Alaska and around the remote areas of the USA (United States of America).


Aircraft using aviation GPS navigation equipment must be equip with the legal and operational alternate means of navigation appropriate to the flight. Active monitoring of alternative navigations equipment is not require if the aviations GPS receiver uses RAIM (Receiver autonomous integrity monitoring) for integrity monitoring. However, active monitoring of an alternate means of navigation is require when the RAIM capability of the aviations GPS equipment is lost.

Aviations GPS is far-off navigational assistance. However, this technology is undoubtedly the most precise system used in navigation by civil and military aircraft. As for ensuring a large and admirable coverage area, we must place the GPS transponder (satellites) far away in outer space at roughly 20,000 km from the earth’s surface. As a result, aviations GPS has become an outstanding navigation tool ever invented due primarily to its accurate position and large coverage area.
