How Non-Directional Radio Beacons Help With Navigation

Great strides have been made in location-based technology since the times when sailors employed a crude compass to navigate their way across uncharted waters. Today, a global positioning system (GPS) is preserved by the USA authorities, and also this navigation tool permits the owner of a recipient to ascertain their location by communicating using four or more GPS satellites. This technology has a number of applications and plays a vital part in operations done by the military, civil, and business users. GPS technology even helps pilots navigate commercial atmosphere.

As additional improvements have been made in the area of GPS technology, some organizations have turned into more sophisticated devices to attain their monitoring needs. For example, differential GPS apparatus and non-directional radio beacons are used more often by classes requiring a higher degree of location accuracy. This article will take a good look at these two location-based technology options.

Differential GPS devices

These apparatus are known chiefly for their improved accuracy. Professionals working in search-and-rescue operations require a higher degree of precision to track down people so that they utilize differential GPS devices. Talk to a Xeos expert. Top-of-the-line units outfitted with this technology boast accuracy to ten cm, whereas conventional GPS devices promise accuracy within fifteen meters. The motive differential GPS products offer you such a high degree of accuracy is that they communicate with a community of stationary, ground-based systems to measure location. These systems take a known, fixed place that’s compared to the location measured by traditional GPS systems. The ground-based devices then compare the measurement with the known place to produce a digital correction signal. This digital correction signal permits the differential GPS device to provide more accurate measurements when locating individuals or apparatus in mountainous regions, in the sea, or in locations where a mobile phone is not able to reach service. A satellite-based augmentation process is comparable, with the exception being it uses orbiting satellites rather than ground-based systems to transmit alterations. Click here to get started!

Non-Directional Radio Beacons

Non-directional radio beacons are wireless transmitters located at a known location and are most frequently used for aviation and marine navigation. Unlike a number of the GPS tools mentioned above, non-directional radio beacons do not utilize location information to provide directions. All these beacons emit signs in their own fixed location, which pilots may use to ascertain where they are situated. Signals also indicate that specific pathway an airplane should follow, which means in-air crashes are prevented by setting aside specific airways for every single aircraft.

The signals that non-directional radio beacons emit follow the curvature of the planet, which makes these signs more beneficial than VHF omnidirectional range signals. In essence, these signs can be obtained at a lower altitude from a larger distance. But, VHF omnidirectional range signs are even more prevalent in developed countries, while non-directional radio beacons are somewhat more prevalent in undeveloped areas or densely populated areas of developed nations.

Sailing Safety Equipment – Emergency Locator Beacons, an Intro

As more people spend time on leisure activities the amount of individuals sailing can be increased. For those looking to set sail on boats larger than the smallest dingy using a placing device which can alert the authorities and send your location in the event of an emergency isn’t only helpful but may be the difference between life and death.

Traditionally the safety equipment that a yacht carries is a VHF radio and distress flares. But sometimes events can occur which mean that you may not have sufficient time to contact anyone with your onboard radio; for example, a devastating failure of the ship due to hitting a submerged object like a subway or a stone could mean that the ship sinks in not much more than a couple of minutes. In such situations, all you have time for is to get your own life raft and grab bag of survival rations etc and be sure that everyone has escaped. In case you’ve got an emergency locator beacon, you can activate this is actually in a matter of moments. Once activated it will, via the COSPAS-SARSAT satellite program contact with the search and rescue authorities where the beacon was registered; then they will subsequently, having assessed with all the contact details left once the beacon was registered to authenticate the telephone, notify the local coastguard or search and rescue services at the country or region that the sign has come out of. The exact place is sent as GPS coordinates or, if GPS is not essential to this beacon product, by triangulating between different satellites that are utilized from the COSPAS-SARSAT system.

There are two chief types of emergency beacon; All these are the EPIRB (Emergency Position Indicating Radio Beacon) and PLB (Personal Locator Beacon). The latest EPIRBs and PLBs both operate on 406 MHz. An EPIRB tends to be larger than a PLB and may either be saved in an Auto-housing, which triggers the EPIRB as it comes in contact with water or as one unit which is triggered by means of a button or switch. Once activated they will continue to transmit a signal for a minimum of 48 hours. They’ll also float. A PLB will have a tendency to be much smaller compared to an EPIRB (often no longer than the size of a mobile telephone ), doesn’t trigger automatically, and does not float, but occasionally it can do if it is stored in a flotation pouch. It is going to only transmit for a minimum of 24 hours.

Generally, an EPIRB is enrolled to a ship, while a PLB is registered to a person. So depending on how big the boat and the number of crews you’ve you may select either an EPIRB or a PLB. Kannad Marine delivers a range of EPIRB and PLB goods suitable for sailing.
