Adventures of a Cold War Fast-Jet Navigator
HK$ 162.00 HK$ 202.00
Kobo

David Herriot served almost 40 years in the Royal Air Force as a navigator, first on the Buccaneer S2 and subsequently on the Tornado Gr1. This volume recounts his early career operating the Buccaneer on three operational flying tours plus a tour as an instructor on the Operational Conversion Unit. With almost 2500 hours on an aircraft that was operated at high-speed, in all weathers and at ultra low-level, his task in the rear seat was a demanding one. But Herriot was more than just the guy in the back of a Buccaneer; he was, quite routinely, and often to the exasperation of his seniors, the life and soul of any party that was taking place either at home base or when overseas defending the flanks of Nato. This is an epic adventure for the aviation enthusiast, particularly those with affection for the Blackburn Buccaneer, and is one that provides a great deal more than the usual introduction to a specific aircraft type and the people who flew it. Here the reader will find an absolute insight into life on a fast jet squadron, at work and mischievous play during the Cold War and they will be introduced to some of the modern Royal Air Force's greatest characters.

How Does the GPS System Work

GPS has become a staple service that many Hong Kongns are utilising today. Many Hong Kongn drivers use GPS devices to guide them on the best routes to use to reach a designated destination. GPS systems are accessible via our smartphones and a variety of handheld GPS devices. Some cars also have come with built-in GPS systems for you to navigate your trips easily.

Despite being used almost every day, not many people know how the GPS works. Most people know that GPS, short for Global Position System, basically uses satellites to determine the position of your location and the destination you are heading to. Here is an in-depth insight into how the global positioning system (GPS) works:

Founding of the Global Positioning System

The Global Positioning System, also known as NavStar was built by the US military system and has been fully operational since 1995. The system was initially developed for military navigation but now anyone with a GPS device, be it a mobile phone or a handheld GPS unit, can receive the radio signals broadcasted by the satellites from outer space. The GPS system currently has 31 active satellites orbiting the Earth from 20,000 kilometres away, making two complete orbits a day. Not all are used though as some are spare satellites in case one malfunctions.

Concept Behind the GPS System

GPS uses a lot of complex technology to operate but the concept is relatively simple to understand. The satellites are arranged in such a way that no matter where you are on the planet, there will be at least four GPS satellites that are “visible” at any point of time. Each of these satellites will transmit information about its position and the current time at regular intervals. Your GPS receiver which will analyse and calculate the high-frequency radio signals emitted by the GPS satellites to determine the distance of the satellite based on how long it took for the messages to arrive. Once your device is able to calculate how far away at least three satellites are, it can pinpoint your location through a simple mathematical principle known as trilateration.

Trilateration

To understand trilateration, you need to imagine yourself standing somewhere on Earth with three satellites in the sky above you. If you are able to know the distance you are from one satellite, say Satellite A, then you will be able to build an imaginary circle with the distance you are from the satellite as the radius. By doing the same thing for satellite B and C, you can work out your location by defining a point where these three circles intersect. This is how your GPS receiver determines your location with the only difference is that it uses overlapping spheres instead of circles.

Although an approximate position can be determined with only three satellites but to improve accuracy and obtain precise altitude accuracy, having information from four or more satellites will be ideal.
