how to calculate distance and course from gps

The formula you need is S = UT + 0.5AT 2 where S = distance, U = initial speed, T = time and A = acceleration. If you assume that the speed is constant between one GPS reading and the next that can reduce to S = UT for that interval. The just add up all the S values for all the intervals.

How does GPS calculate distance?

For this divide the values of longitude and latitude of both the points by 180/pi. The value of pi is 22/7. The value of 180/pi is approximately 57.29577951. If we want to calculate the distance between two places in miles, use the value 3, 963, which is the radius of Earth.

How do you calculate distance using latitude and longitude?

How do I calculate distance using latitude and longitude on Google Maps?

The formula for calculating longitude distance is: "Dep = d. long * Cos Mid. Lat" Dep is the same thing as miles.

How do you convert latitude to distance?

One degree of latitude equals approximately 364,000 feet (69 miles), one minute equals 6,068 feet (1.15 miles), and one-second equals 101 feet. One-degree of longitude equals 288,200 feet (54.6 miles), one minute equals 4,800 feet (0.91 mile), and one second equals 80 feet.

What is the formula for distance between two points?

What is Distance Between Two Points Formula? Distance between two points is the length of the line segment that connects the two points in a plane. The formula to find the distance between the two points is usually given by d=√((x2 – x1)² + (y2 – y1)²).

How do you Measure distance on a map in geography?

A quick way to measure distance is to count each square you cross on the map. On your Ordnance survey map each grid square measures one kilometre from side to side and from top to bottom. If you go diagonally across a square, the distance will be a bit longer – about 1.5 km.

How many miles is 2 degrees longitude?

Each degree of latitude is approximately 69 miles (111 kilometers) apart.

How many km is a degree of longitude?

about 111 kilometersA degree of longitude is about 111 kilometers (69 miles) at its widest. The widest areas of longitude are near the Equator, where Earth bulges out. Because of Earth's curvature, the actual distance of a degrees, minutes, and seconds of longitude depends on its distance from the Equator.

How many km is a degree of latitude?

about 111 kilometersOne degree of latitude, called an arc degree, covers about 111 kilometers (69 miles). Because of Earth's curvature, the farther the circles are from the Equator, the smaller they are. At the North and South Poles, arc degrees are simply points. Degrees of latitude are divided into 60 minutes.

What is the formula for distance between two points?

What is Distance Between Two Points Formula? Distance between two points is the length of the line segment that connects the two points in a plane. The formula to find the distance between the two points is usually given by d=√((x2 – x1)² + (y2 – y1)²).

What is the distance between two latitude longitude points?

approximately 69 milesEach degree of latitude is approximately 69 miles (111 kilometers) apart. At the equator, the distance is 68.703 miles (110.567 kilometers). At the Tropic of Cancer and Tropic of Capricorn (23.5 degrees north and south), the distance is 68.94 miles (110.948 kilometers).

What is GPS format?

What is most often known as GPS format (though not all GPS units use it or agree on it...), is displayed as (DDD,MM.MMMM) in which seconds are converted to decimal minutes, as a minute value. Seconds have the value of 0 to 60, with 0 and 60 (usually designated as 0 to 59 and then restarting at 0) being the same value, minutes have the same characteristics and degrees are valid from 0 to 180 and 180 to 0, (0 and 180 do NOT have the same value) both North and South of the equator, and East and West of the prime meridian. Now that the designations (and reasons for them) are perfectly clear, here is the set of formulae if you need to do this manually.

Why is GPS information so readily available?

Due to the fact that GPS information is so readily available now for daily weather information, automotive use, aviation, marine and personal use, many companies have set their own standards as to how that information is displayed and disseminated.

How many minutes are in a degree?

There are 60 minutes in a degree and 60 seconds in a minute (3600 seconds in a degree), both seconds and minutes are segments of ARC and not time. There are 360 degrees in a complete circle or sphere but in all longitude measurements, the total of the degrees is expressed as 2 halves of 180 degrees each, moving East and West from the prime meridian.

How many decimal places are there in degrees?

There is ONLY a degree designation. (DDD.DDDD) A maximum of 4 decimal places is adequate.

Coordinate Converter

This form will try to read whatever you enter and convert it to three formats: decimal degrees, degrees-minutes, and degrees-minutes-seconds.

Calculate the great circle distance between two points

This calculator will find the distance between two pairs of coordinates to a very high degree of precision (using the thoroughly nasty Vincenty Formula, which accounts for the flattened shape of the earth). The "Draw map" button will show you the two points on a map and draw the great circle route between them.

Calculate the distance between two addresses

This calculator will find the straight-line (great circle) distance between two locations of any kind: street addresses, city names, ZIP codes, etc. (The coordinates of the locations are provided by the Google Geocoding API.) NOTE: If you just need the coordinates of an address, use the geocoding utilities.

Draw a direct route between airports

This form will simply show you two airports — represented by a 3-letter IATA code or 4-letter ICAO code — on a map, along with a line representing the shortest route between them (and the distance, of course).

Draw routes between multiple airports

In the form below, you can enter a list of routes (airport pairs) separated by commas to see all of them, and their distances, on a single map. For example: PDX-MSP, BOS-MIA, ATL-DEN, DEN-PHX

Draw range rings around a point

This "circle generator" will plot a point on a map — given a set of coordinates or other location (an airport code, postal code, city/state pair, or coordinate pair) — and draw a circle, or circles, around that point.

Find the coordinates at a given distance and bearing

This form will tell you what point lies at any distance and bearing from another point, along a great circle path. If you don't supply units in the distance box itself (e.g., "100 mi"), it will default to kilometers. (The formula used here was adapted from "Sprong" by Dale Bickel at the FCC.)

What is the compass used for in a smartphone?

In a smartphone, the display of the heading may be assisted by the internal compass.

What does Doppler Shift do for GPS?

GPS receiver use Doppler Shift for speed and probably also for heading calculation.

How to determine heading in a car?

In a car, the heading is deduced from the trajectory, by looking at the previously recorded points (Doppler based speed measurement is not widespread on cheap devices). And, as stated in other answers, this is not the heading but the track which is displayed (the direction you are moving to, compared to the direction you are facing). Luckily, cars don't drift (most of the time) and so, the track is equal to the heading.

Where is the 90° of the protractor?

Wherever you are on the globe, you should be able to lay on the ground a protractor whose 0° is aligned with your current meridian, pointing north, and the 90° is aligned on the local parallel, toward the east. Hence you can read your heading everywhere (except on poles)

Is heading the same as course?

heading and course is the same for a vehicle, But not for a ship (due drift).

Does GPS receiver calculate heading?

Precisly a GPS receiver does not calculate heading.#N#heading is the direction where you are looking to.#N#The more correct term is course or course over ground.#N#But modern APIs often intermix heading, course and bearing.
