Interesting facts about GPS technology

Global Positioning Systems (GPS) are a critical component when it comes to the use and application of many of the technologies, on a daily basis. Although the system was primarily designed to navigate using signals which accurately pinpoint your location, nowadays GPS and navigation systems are a common technological fixture.

However, there are many things you didn’t know about proprietary GPS and navigation systems although we are pretty much relying on the same for proper guidance. Here are a few interesting facts about this three-decade-old technology.

GPS and navigation technology: The concept which revolves around GPS technology may be similar, but the technology is not unique. This means GPS is not the only space-based radio navigation systems. It is one of the much popular and used systems globally. Russia has its own navigation system known as the GLONASS, along with Galileo in Europe and BeiDou in China. However, presently GPS and GLONASS are the only two satellite-based space radio systems that offer global coverage. The Galileo and BeiDou systems are yet to be made fully functional for global coverage.

Number of Satellites in orbit: Since GPS and navigation systems heavily rely on global satellites for positional and coverage accuracy of the signals, there are currently 32 satellites orbiting our planet. Global coverage is only possible when a total of 24 satellites work together in cohesion to provide uninterrupted signals and coverage, which was achieved back in the 90’s itself. However, today with the additional eight satellites, extra coverage is possible without any downtime when the GPS satellites are undergoing scheduled maintenance and repairs.

GPS visibility and line of sight concept: We may have 32 satellites orbiting at any given point of time, however, for GPS and navigation systems to function properly, we only need a minimum of four satellites to achieve positionally and signal accuracy. Four satellites in our line of sight will ensure uninterrupted coverage and accurate location mapping since there is constant communication between the signal sender and receiver. The signals travel at the speed of light which is constant and based on these factors it is easy to determine an accurate position for mapping.

Relativity plays a key role: Albert Einstein’s theory of relativity in simple terms states that time tends to move faster in places where there is the minimum effect of gravity, which is why the time onboard GPS and navigation satellites will be different when compared to our clocks back home. In fact, the difference of 38 microseconds faster per day will not sound so significant, but in reality, if this factor is not taken into account, the locations mapping could be off by more than a couple of miles thus affecting positional accuracy. This is also one of the main reasons why we need four orbiting satellites in line of sight to determine accuracy.

The government owns and operates GPS system: The technology might have been invented and developed by the military, to be used for advanced warfare and systems, but it was made freely available to the public after 2000. The technology is owned and operated by the government as a public domain for everyone to benefit from GPS and navigation systems which have become a major part of our routine.

Other uses of GPS:

  • GPS is not just for determining your location, but also can be used to find out the exact time also with the help of onboard atomic clocks.
  • GPS and navigation shoes are designed for people who are suffering from Alzheimer’s so that they can be tracked in case they lose their way.
  • Not only automobiles, but ships and planes are also very dependent on this technology to navigate safely across continents.

  • Best mountain biking techniques for beginners

    Are you a beginner who wants to experience the awesomeness of mountain biking? Read on to know the right technique that could help you enjoy your ride to the fullest.

    The key to have the best mountain biking journey is to be flexible and relaxed. Mountain biking is different from a commute or a road ride where the biker merely sits and spins. You should not be rigid to move forward or backward or off the side. Riding flat, descending, climbing and cornering are some of the things you would need to constantly do while on your mountain ride. Each movement requires a technique, let us quickly walk through them!

    If you are riding on a flat terrain, the best technique is to pedal at a steady pace. You could either be sitting or standing while you pedal. Looking in the forward direction is the key. While you are riding, make sure you focus even down the trail and not merely on your front wheel. As soon as you see obstacles, climbs or descents coming, make sure you have the time to brace yourself up to navigate through them.

    If you are on a descent, stand up resting on your pedals and keep both your arms and legs flexed. These help as additional shock absorbents and help you pass bumps easily. When you are going down hill, remember to keep your body low, knees and elbows bent and hips bent.

    When you are supposed to climb, it is important you anticipate the incline a little in advance. This would help you drop into an easy gear well in time to prepare for the journey uphill. Instead of standing and aiming to pedal hard, you must sit and spin the pedals at a steady pace. Steadily pedaling uphill would help you to climb smoothly and not loose traction or stop. To develop traction, it is required that you maintain your weight on the back wheel. If you wish to steer, the weight should be exerted towards the front wheel.

    Once you know the basic techniques like riding on a flat terrain, climbing and descending, you could orient yourself to cornering. The basic idea is to manage your weight and utilize your muscles in the right direction. It is important that you practice these techniques well before you go for your first ride. Various trail centers marked by skill and difficulty levels are ideal for inexperienced bikers to practice on. Once you are confident about your technique, you are fit to ride on and enjoy the therapy mountain biking provides!
