Altimeters of various types for mountaineers and others who participate in high-altitude extreme sports.

Are you interested in learning more about the many kinds of altimeters? Then you’ve come to the right place.

Let’s discuss these popular and practical electronic devices!

Climbers and athletes who participate in extreme sports might benefit greatly from the use of an altimeter since it provides them with information on their current altitude. Paul Kollsman, a German-American inventor, came up with the idea in 1928 and patented it. The pressure altimeter was Kollsman’s take on the altimeter, but technology has come a long way since then, and there are now many other kinds of altimeters on the market. Kollsman’s Altimeter was a pressure altimeter. In this extensive tutorial, we will go through the many kinds of altimeters that are used by climbers and those who participate in extreme sports at high altitudes. Let’s get into it.

Why Is Altitude Important for People Who Climb and Participate in Other Extreme Sports at High Elevations?

When it comes to mountain climbers, altitude is one of the most important factors to consider. As a result of the decreased air pressure at higher altitudes, the quantity of oxygen in the air becomes less concentrated. In addition, climbers at high altitudes need an adequate amount of oxygen to guarantee their continued existence.

When it comes to mountaineering, climbers have to make a lot of judgments based on a variety of circumstances, including the weather and the conditions of the route.

When you embark on an adventure to a well-known mountain like K2 or Mount Everest, you need a full team of specialists who will continually check the conditions of the weather and any other potential dangers.

Additionally, there is a group of trained specialists that accompany you on your journey and provide you with oxygen cylinders so that you always have an adequate amount of oxygen.

When it comes to extreme sports like wingsuit flying, base jumping, and skydiving, the athletes require an altimeter so that they know when to deploy their parachutes. Other extreme sports include base jumping and base jumping.

The athletes are able to determine their precise altitude thanks to the altimeter, which gives them the information they need to deploy their parachutes at the appropriate height. This keeps sportsmen safe.

The Altimeter is also used by climbers and hikers of a more casual nature. Although it is not generally seen as an essential piece of equipment for hikers, it is possible to use it to figure out how high you are.

Numerous sports timepieces are equipped with a capability called an altimeter, which informs the wearer of their current altitude as well as other pertinent statistics.

What kinds of altimeters are available for mountaineers and other people who engage in extreme sports at high altitudes?

There are two distinct varieties of altimeters that may be purchased for use by mountain climbers and athletes participating in high-altitude extreme sports.

  • Altimeters that measure pressure or barometric pressure
  • GPS Altimeters
  • Pressure Altimeters

The Pressure Altimeter 

This is the form of the altimeter that was designed by Paul Kollsman. It is the oldest kind of altimeter that is still available on the market. For the purpose of this altimeter, you will be relying on the pressure of the surrounding air to make your determination. The pressure of the atmosphere is greatest close to the surface of the planet, and it gradually lowers with increasing altitude.

When your altimeter has a measurement of the atmospheric pressure, it compares that reading to a value that you have already specified, which allows it to calculate your altitude. When it comes to the accuracy of pressure altimeters, there are a number of things that might impact their accuracy. Some of these reasons include the weather and faulty calibration.

Pressure altimeters are regarded as having a high degree of accuracy since they continue to provide almost correct readings even in harsh environments. However, if you are a novice and you get a manual altimeter, it will be challenging for you to interpret the information included inside.

If you are unfamiliar with altimeters and would like to learn how they function, you can learn all you need to know by reading our comprehensive guide, in which we describe the operation of altimeters in great depth.

GPS Altimeters

The Global Positioning System (GPS) is used by most modern smartwatches and altimeters to provide an accurate reading of the user’s current height.

The Global Positioning System (GPS) was once a top-secret military project, and the only people who were permitted to use it were members of the United States Armed Forces and other approved people.

However, the United States made it available to the entire public, and it is now integrated into the positioning systems of our cellphones and other electronic devices.

The GPS altimeters are equipped with the GPS chip, which determines your precise location by using a method known as triangulation. The triangulation method pinpoints your location more precisely by using all three of the GPS satellites.

The GPS Altimeter will next make use of the remaining 4 GPS satellites in order to determine your elevation. In this manner, contemporary technology is used by GPS altimeters in order to determine your altitude.

GPS altimeters, similar to pressure altimeters, may not always provide accurate readings. The weather is the most significant aspect that may play a role in reducing the accuracy of the GPS Altimeter. Additionally, GPS signals may be disrupted if you are in a tunnel, the jungle, or near large structures.

There Are Other Kinds of Altimeters

There are more than just pressure altimeters and GPS altimeters that fall under the category of altimeters. There are also various sorts of altimeters on the market, such as ones that are made specifically for satellites and aircraft.

Radio Altimeters

Radio altimeters are a form of altimeter that is considered to be of a higher technological level than their counterparts, and as such, they are used by both commercial and military aircraft. Radio altimeters make use of radio technology to provide an accurate reading of your altitude, as the name says.

Due to the fact that radio waves move at the speed of light, it only takes a few seconds to accurately calculate the altitude of an object. The pace at which sound waves move is 300,000,000 km per second, which is equivalent to 186,000 miles per second.

The radio beam is directed toward the ground so that the reflected radio waves may be picked up by the receiver. This is how the system works.

Because the radio altimeter is not affected by issues like weather or poor signals, it is used by a wide variety of aircraft, including jet fighters, commercial aircraft, and other kinds of aircraft as well.

Laser Altimeters

The operation of laser altimeters is quite similar to that of radio altimeters. However, laser altimeters make use of infrared light rather than radio waves.

In order for it to function, the infrared beam is first directed toward the ground, and then, using mirrors and lenses, the reflected beam is collected and focused on the photocell detector, which is sensitive to infrared light.

During flight, the laser altimeters will consistently cast the beam, at which point they will measure the aircraft’s height and draw its topographical map. The term “Laser altimetry” may also be used to refer to this method, as can “Light Detection and Ranging” (LIDAR).

Space probes use this method in order to ascertain the topographic characteristics of other planets’ surfaces. The Mars Global Surveyor (MGS) and the Mars Orbiter Laser Altimeter, which is NASA’s version of the Laser Altimeter, both make use of technology developed by NASA (MOLA).

Bottom Line

That wraps things up, people. These are the many kinds of altimeters that may be found in the world, although the only ones that can be purchased commercially are pressure altimeters and GPS altimeters. If you are interested in purchasing one for yourself, check out our buying guide for climbers to see which altimeters are considered to be the finest on the market today. Also, if you want to know how altimeters work, you can look at our guide, which has a full and detailed explanation of everything you need to know to understand how altimeters work.
