when using a gps for navigation, “desired course” can best be defined as:

Is there a difference between course information and GPS navigation information?

Oct 04, 2007 · While the COG will be 270T, your boat’s heading will be greater than 270T, because you must crab into the current to make good the desired course. A sophisticated navigation computer can take speed through the water from a transducer and compare it with ship’s heading (from a compass system), SOG and COG to come up with current set and drift, a task that used …

How does a GPS navigation system work?

Jun 24, 2018 · Most GPS navigators present a function called DTK—Desired Track. What exactly is that? In the old days of paper charts, the Desired Track was the line on the chart from point A to point B drawn while still sitting in your chair at home. …

How does the GPS guide you to the next waypoint?

The GPS will provide navigation along the desired course to the waypoint and rejoin the approach in sequence from that point on. To activate a new approach for the same airport, select the new procedure from the Procedures page. To activate a new approach to …

What is DTK—desired track in GPS navigation?

Mar 14, 2022 · Using such on-the-ground navigational aids as handrails (long linear features such as rivers, roads, or powerline corridors roughly aligned with your desired course of travel) and catchpoints (mapped landmarks along a handrail that peg your location), you can cover a lot of ground without peeking at your compass.. But the point is, you should have a compass to peek …

How is course similar to bearing?

Course. Course is very similar to bearing in that it’s the desired direction for your route of flight. If you are going directly from one airport to the other, your course and bearing will be the same along the route of flight. If you are flying from an airport to a VOR to another airport, your course will change in each leg, as will your bearing.

What is the difference between a track and a heading?

Heading is the direction the airplane is pointed, whereas track is the actual direction of the airplane tracking across the ground. Bearing is the angle between any two points, whereas course is your intended path of travel to your destination. In the rest of this post we’ll elaborate on each of these points and then also provide ...

What is heading in airplanes?

This does not factor for wind, or the actual movement of the airplane across the ground. It only refers to what the compass reads based on where the nose is pointed.

Why is bearing confusing?

Bearing can be confusing sometimes because has some overlap with course. Bearing is simply the angle or direction between two points. A practical application of this is in VOR navigation. It’s a common thing to hear someone say “we are bearing 090 from the station”.

What is the DTK on a GPS?

What exactly is that? In the old days of paper charts, the Desired Track was the line on the chart from point A to point B drawn while still sitting in your chair at home. We called it our Course—but it’s the same thing. That line on the chart never changed no matter how far from it you flew once airborne. It’s what you desired to do, but not necessarily what you did.

What does RAIM stand for in GPS?

They assume it is a way to tell if the GPS is having a bad day. RAIM stands for Receiver Autonomous Integrity Monitoring. That’s a long-winded way of saying the receiver checks itself and tells you if there is a problem.

What is OBS mode?

OBS mode is also often misunderstood. The simplest way to think about OBS mode, is to imagine that when you push the OBS key you are telling the navigator to treat the current waypoint (the one to which you are navigating at the moment) as if it were a VOR.

Do IFR pilots know their GPS?

Too many IFR pilots don’t know their GPS as intimately as they should. Hitting “Direct To” and their destination is as much as many can muster out of their navigator. There is a serious lack of knowledge of what the GPS is trying to tell them.

What is a GPS?

The GPS is designed to complement your printed approach plates and vastly improve situational awareness throughout the approach. However, you must always fly an approach as it appears on the approach plate. The active leg (or the portion of the approach currently in use) is depicted in magenta on the Map page.

How does GPS work?

GPS, or global positioning system, is a network of satellites that transmit coded data that receivers on the ground can use to determine their position on earth. GPS receivers determine location by comparing the angular relationships between the receiver and orbiting satellites. In this way, GPS is really quite similar to celestial navigation, ...

What is the beauty of GPS?

Part of the beauty of the new generation of GPS devices is their portability. Also, if you are parked in a large parking lot, such as a stadium, amusement park, or mall lot, set your car's position as a waypoint and you'll never lose track of your car again.

How to prevent theft of GPS?

Preventing Theft. Remove your GPS and its windshield suction mount from your windshield and stow it out of sight every time you park in a public place. GPS units are common targets for thieves and their high-tech, visible nature makes them ideal for smash-and-grab style larceny.
