Global Positioning System (GPS) is often, but this is not a new technology. Dr. Ivan Rettig began to develop GPS tracking technology in the 1960s, with funding from the U.S. Department of Defense (DOD). Today, this technique is used to determine the precise location of a vehicle, person, or other asset classes. However, this technique is not capable of accurately individuals such as search and rescue professionals or wildlife researchers need to deliver their work to be done. These professionals differential GPS devices that will be capable of a positional accuracy of the standard fifteen meters accuracy improves with GPS based on ten cm.
Differential GPS device provides accurate and precise results with localization of a network of reference stations on the ground. These systems are positions that are consistent and well known are fixed. Differential GPS device measures the received signal from the satellites, and compares it with the signal from the lower reference systems, and then provides a digital correction signal, to take account of the different measures.
Today, when individuals, researchers, government agencies, or anyone else who needs to acquire this technology is the best option to acquire NAVTEX transmitter. The remainder of this article will take a look at why these new devices are better than differential GPS devices.
Buyers have two options when evaluating NAVTEX transmitter: SV1500 SV3000 and the. Both machines can be purchased in the form of the dual system, which means that the system contains two channels and an external controller, arbitrage transactions switching from one device to another in case of failure. This allows easy maintenance and allows the operator, are convinced that the differential GPS equipment is ready at any time.
As the NAVTEX transmitter can also remotely via RS485 through a remote offers full control to monitor. These devices provide monitoring functions with an integrated Ethernet server and an Ethernet connection simple, no additional software is purchased. Users can also find out who is intuitive and easy to follow with a membrane keyboard with which checks user input.
Each unit also meet test equipment integrated system that allows users to perform troubleshooting any position. An LCD display on the surface of the device allows operators NAVTEX transmitters display test data point within a specific channel, while a microcontroller automatically monitors critical parameters are sensitive preset steps abnormal conditions.
The main difference between the SV1500 SV3000 and devices, the amount of RF power output, the number after the “SV”, which is the number of watts (W) for an initial period of 50 ohms. Energy consumption for SV1500 NAVTEX transmitter is 2000 W 1500 W RF output while the device uses for SV3000 3000 W 3750 W RF output. Both devices comply with Federal Communications Commission (FCC) standards, so that the decision is a major buyer owes what W RF output is required.
When it comes to buying a differential GPS equipment is provided, buyers find NAVTEX stations ensures easy maintenance and greater ease of use.
