Great strides have been made in location-based technology because the times when sailors employed a crude compass to navigate their way around uncharted waters. These days, a global positioning system (GPS) is maintained by the United States government, and also this navigation instrument allows the owner of a receiver to determine his or her location by communication using four or more GPS satellites. This technology has a range of applications and plays a very important part of operations done by the army, civil, and business users. GPS technology even helps pilots navigate commercial atmosphere.
As additional advancements are made in the field of GPS technology, some organizations have turned into more sophisticated devices to attain their tracking requirements. For instance, differential GPS apparatus and non-directional radio beacons are used more often by groups requiring a higher level of location accuracy. This article will take a closer look at both of these location-based technology options.
Differential GPS devices
These apparatus are known primarily for their improved accuracy. Professionals working in search-and-rescue operations need a higher degree of precision to track down individuals so that they use differential GPS apparatus. Top-of-the-line units equipped with this technology boast precision to ten cm, whereas traditional GPS devices guarantee accuracy within fifteen meters. The reason differential GPS products offer you such a high level of accuracy is that they communicate with a community of fixed, ground-based systems to measure location. These systems carry a known, fixed position that is compared to the location measured by traditional GPS systems. Contact Xeos about GPS. The ground-based apparatus then compare the measurement with the famous location to produce a digital correction signal. This digital correction signal permits the differential GPS device to supply more accurate measurements when locating people or devices in wooded areas, in the sea, or in locations where a mobile phone is not able to attain service. A satellite-based augmentation process is comparable, with the exception being it uses orbiting satellites instead of ground-based systems to transmit corrections.
Non-Directional Radio Beacons
Non-directional radio beacons are radio transmitters located at a known location and are most frequently used for marine and aviation navigation. Unlike some of the GPS resources mentioned above, non-directional radio beacons don’t use location information to provide instructions. All these beacons emit signs from their fixed location, which pilots can use to ascertain where they are situated. Signals also indicate which specific pathway an airplane should follow, so in-air collisions are prevented by setting aside specific airways for each aircraft. Click here to get in touch!
The signs that non-directional radio beacons emit follow the curvature of the Earth, which makes these signs more beneficial compared to VHF omnidirectional range signals. Essentially, these signs can be received at a lower elevation from a greater distance. But, VHF omnidirectional range signals are actually more common in developed countries, while non-directional radio beacons are somewhat more common 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 number of people sailing can be increased. For those looking to set sailboats larger than the tiniest dingy the use of a location device which can alert the authorities and send where you are in case of a crisis is not only useful but may be the difference between life and death.
Traditionally the security equipment a yacht carries would be a VHF radio and distress flares. However, sometimes events can happen which mean that you may not have sufficient time to contact anybody with your onboard radio; for example, a catastrophic failure of the boat because of hitting a submerged object such as a subway or a rock could mean that the boat sinks in not much more than a couple of minutes. In such situations, all you’ve got time for is to get your own life raft and grab bag of survival rations etc and ensure that everybody has escaped. In case you have an emergency locator beacon it’s possible to trigger this is in a matter of seconds. Once activated it will, via the COSPAS-SARSAT satellite system contact the search and rescue authorities at which the beacon has been registered; they will then, having checked with all the contact information 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 signal has come out of. The exact location is sent as GPS coordinates or, if GPS isn’t integral to this beacon product, by triangulating between the different satellites that are used from the COSPAS-SARSAT system.
There are two chief kinds of emergency beacon; These will be the EPIRB (Emergency Position Indicating Radio Beacon) and PLB (Personal Locator Beacon). The latest EPIRBs and PLBs both operate on 406 MHz. An EPIRB will be bigger than a PLB and can be saved in an Auto-housing, which triggers the EPIRB when it comes in contact with water or as a single unit which is activated by way of a button or change. Once activated they will continue to transmit a signal for a minimum of 48 hours. They will also float. A PLB will tend to be much more compact than 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 will only transmit for a minimum of 24 hours.
Generally, an EPIRB is enrolled to a boat, while a PLB is registered to a person. So based on how big the ship and the number of crews you’ve you may choose either an EPIRB or a PLB. Kannad Marine delivers a range of EPIRB and PLB products acceptable for sailing.
