How to use COMPASS in the iPhone for orientation. Calibrating the compass iOS 10

Roman It used to require manual calibration when running the COMPASS app. The new iPhone has never asked for this, but the maps do not correctly display the position of the smartphone. Indeed, the procedure of manual calibration at application launch is missing in latest versions of iOS. The accuracy of this sensor is now guaranteed by the geolocation module.

To always have the most accurate display, go to Settings. Privacy. Geolocation Services (Main switch must be activated) and allow the COMPASS app to access geolocation while using the program.

How to use the iPhone Compass!!

Restart the app (end it from the multitasking panel and open it again). iPhone will either ask to calibrate COMPASS manually, or will indicate correctly the direction of light by itself.

After calibration you can disable access to geolocation, so when the compass is working the iPhone will not use the GPS module and will save battery power.

You can go further to Settings. Privacy. Geolocation Services. System Services and activate the Compass Calibration switch. So every time you start the app, the iPhone will check the compass with the geopositioning sensor, but the GPS will not be active the whole time the app is running.

Initial information about the “COMPASS” program

COMPASS helps you determine direction, find longitude and latitude, align level, and determine deviation.

To find out where you are at the moment, select “Settings” “Privacy” “Geolocation” and turn on “Geolocation Services” and “COMPASS. For more information about using Geolocation Services, see. See Privacy section for more information on using Geolocation Services.

Tap the screen to lock the current direction, then watch the red bar to stay on course.

Magnetic fields and other environmental conditions can affect the accuracy of compass readings; even magnets in your iPhone headphones can cause deviation. Use digital COMPASS only for basic navigation orientation. Don’t rely on its readings to determine your exact location, proximity, distance or direction.

How to use the COMPASS and iPhone Level

All Apple iPhones released since the iPhone 3G in 2008 are equipped with a digital compass and level, permanently putting a few handy tools in your

Using your iPhone’s built-in compass

To access the compass, start by launching the COMPASS app. Which is displayed by default on all current iPhone models. The app is on the home screen, but if you uninstalled it, reinstall it from the App Store for free.

Calibrating the Compass

When the app is launched for the first time, you will be prompted to calibrate COMPASS by rotating your phone 360 degrees. To help the calibration process, follow the on-screen animation that Apple provides. Once your device is fully calibrated, you will be presented with COMPASS itself.

Understanding the Compass

Hold the iPhone parallel to the ground with the screen facing up. You’ll see a small circle with a crosshair in the center of the compass; make sure your hand is parallel to the ground by tilting your hand to align the crosshairs with the center of the compass.

The little red arrow above the letter “N” will always point north, and the long bold white line at the top of the iPhone screen indicates the current direction you are.

Compass directions are usually expressed in degrees. Output your heading by seeing which number matches the long, bold white line at the top of your iPhone screen on the outside of the compass circle, or by indicating a specific number at the bottom of the screen. The current level you encounter will update as you turn your device; this will also show a letter noting which main direction is closest.

COMPASS Tips and Tricks

To keep a close eye on how you are moving, turn to face your destination and tap the center to set your direction of travel. As you move the compass away from this mowing line, you will see a red arc spread out between your estimated course and your current course. To tilt the arc, tap the center of the compass again.

At the bottom of the screen, you’ll also find additional information noting your GPS position (longitude and latitude), your current geographic location, and your level above sea level.

Using your iPhone‘s built-in level

If you want to hang a shelf or picture, you can use the Compass app’s level feature to make sure it’s not tilted or off-center. To use the level, open the Measurement app and tap the Level icon at the bottom of the screen.

The level tool was originally bundled with the compass, but in iOS 12 the tool has moved to the Measure app instead. However, the functionality remains unchanged.

Level Calibration

To use the level, calibrate the application with a point that you have already deemed to be fully primed. You can then digitally note how far your item is from the perfect alignment with the original surface.

For example, if you are hanging a painting on the wall and want it to be level with the floor, you would place your iPhone on a flat surface against the wall, which tells the device that you are operating on a vertical axis. You would then move your iPhone to the top or bottom of the wall so that the edge of the device touches the mowing line of the ceiling or floor; this step is important because we assume that the floor and ceiling must be perfectly level

When you make sure your device is in what you consider a level, tap the screen it will turn green for a moment and display the number 0. The level function of your iPhone is now calibrated. You should recalibrate your level every time you switch axes or configure something differently.

Understanding the level

Place a calibrated iPhone level against the object. Rotate the object left and right, keeping your iPhone pressed against it. The number on your iPhone screen will change depending on how offset your object is from what you originally calibrated.

A number of zero will be displayed on the screen when the object is fully aligned, while a range of numbers will be displayed when you are not; these numbers are expressed in degrees and allow us to understand how far away our object is from the level. Just keep rotating your object in the appropriate direction to bring it back to the zero state of perfect level.

Level Tips and Tricks

At any time during the alignment process, you can tap the screen to recalibrate your device if necessary. When you measure along the vertical axis, two small scythes will appear on the left and right sides of the screen. When you measure on the horizontal axis, two circles will appear on the screen.

How to set up and calibrate the Compass app on your iPhone

Digital compasses need calibration. If you are walking, they can usually use the location to determine where you are going. However, if you’re standing still, you may have to play a little game before they act.

  • Launch COMPASS from the home screen.
  • Hold your iPhone in the palm of your hand and follow the on-screen instructions when prompted to calibrate. You will have to tilt your iPhone to roll the ball around the on-screen circle.

After you swipe the ball around the circle, the COMPASS will be calibrated and you can start using it right away!

D Compass

3D Compass is another popular compass app for Android and iOS users that allows you to get a real view on your smartphone. It shows real-time map and GPS information in 3D view on your smartphone. It is only a fun application to get the correct path to your destination.

You can use this app to get true north direction while you’re out. It supports both portrait and landscape mode, so you can also rotate your smartphone depending on yourself.

Access the compass to your geoposition

In case Compass does not display the current location, you need to check the connection of geolocation services.

  • Open “Settings.”.
  • Go to Privacy.
  • Turn on “Geolocation Services”.
  • Tap “COMPASS“, select “When using the application.

Important! Magnetic fields, nearby metal accumulation, other environmental conditions influence the correctness of COMPASS program readings in the smartphone. That’s why digital COMPASS is recommended only as a supplementary navigation aid. To determine the exact location, direction, distance, you can not rely on its readings.

Does the magnetic COMPASS work outside the Earth

Many stars, planets, and their satellites have magnetic fields, but often the magnetic field is so weak that it cannot move the magnetic compass needle. sensitive devices detect even such a slight manifestation of magnetism, but we are not talking about them now.

So, for example, on the Moon it will most likely not be possible to use the magnetic COMPASS for orientation, since the Moon’s magnetic field is very weak.

The same is true for outer space far away from celestial bodies. Here the magnetic fields are usually so small that they are unable to move the magnetic compass needle.

The last statement is only true for a magnetic compass located far away from a spacecraft plowing the expanse of space. On the ISS, compass readings will depend entirely on magnetic deviations, caused exclusively by parts of the space station itself.

On the other hand, you should not forget that even on those planets, where the magnetic field is not less, if not more than on the Earth, the magnetic poles periodically change places, and the direction to the magnetic pole with a high probability does not coincide with the direction to the geographical pole. In principle, as stated earlier, the Earth has the same “trouble” and the fact that today we have the opportunity to use the magnetic COMPASS for approximate determination of direction to the geographical poles, we can say. just a happy coincidence.

Thus, speaking of a magnetic compass as the main means of navigation for a tourist, it is always necessary to keep in mind the limitations of its operation, which, fortunately, are not so many. In most cases, the magnetic COMPASS, when used correctly, will help people orientate themselves in space, if a map is available, determine their location, and find the direction for further movement, including to get to people as quickly as possible in an emergency situation.

If in an emergency situation a person has neither a navigator, nor a compass, nor metal objects from which it could be made, then it remains to orient by the so-called solar compass.

Built-in GPS. this is one of the standard functions of modern smart phones, through which mobile users can use the various navigation applications such as Google Maps and get an accurate location, for example, their own location, to localize an object on the map, create a route of movement, etc.д.

However, different Android devices are equipped with different types of GPS sensors, which in turn differ in their technical parameters.

Accordingly, depending on the quality of such sensors depends on the quality of the GPS-signal, which can provide each individual model of smartphone.

Additionally, other important factors seriously affect the quality of the GPS signal, such as the system settings of the device, the software used, the quality of the connection and even the firmware version of the device.

Steps of determining the azimuth using the “COMPASS” application in the iPhone

There is one incredibly handy application on the iPhone. COMPASS, which is able to determine where the azimuth and the north side of the horizon are. It is the determination of the azimuth that allows you to designate the correct direction of travel and get to your destination.

To correctly determine this indicator, you need not only to download the above application to your gadget, but also to perform several consecutive steps:

  • place the gadget on the map of the area;
  • the right side should be positioned so that it connects the two settlements from which and where you want to get;
  • turn the map of the area so that the arrow pointing north is parallel to the S-S line;
  • At the bottom of the smartphone screen you can find the index of the detected azimuth.

compass malfunction

Faulty COMPASS can also give wrong readings, so before you go on a trip every device you have with you should check it for serviceability.

To do this, hold a magnetized object such as a knife against the side of the compass until the compass needle deflects to the side. After the object causing the magnetic deviation is removed, the arrow should return to the previous position. Do the same with the magnetized object from the other side.

If the arrow returns to its previous position after all the manipulations, this COMPASS will work correctly. If it doesn’t, you mustn’t use it: it’s defective.
