Global positioning system (GPS) tracking has become more common, but it is not a new technology.
Dr.
Ivan Rettig began developing GPS tracking technology back in the 1960s, using funds from the United States Department of Defense (DOD).
Today, this technology is used to determine the exact location of a vehicle, person, or other asset.
However, this technology is unable to deliver a level of accuracy individuals such as search and rescue professionals or wildlife researchers need to complete their jobs.
These professionals turn to differential GPS equipment, which is able to improve location accuracy from the fifteen-meter accuracy that is standard among basic GPS equipment to about ten cm.
Differential GPS equipment delivers more accurate and precise location results thanks to a network of reference stations located on the ground.
These systems have fixed positions that are consistent and known.
Differential GPS equipment measures the signal received from satellite systems and compares it to the signal from ground reference systems, and then delivers a digital correction signal to account for the difference in measurements.
Today, when individuals, researchers, government organizations, or anyone else needs to acquire this technology, the best option is to purchase NAVTEX transmitters.
The rest of this article will take a look at why these new devices are better than differential GPS equipment.
Buyers have two options when evaluating NAVTEX transmitters: the SV1500 and the SV3000.
Both machines can be acquired in dual system form, meaning the system contains two transmitters and an external arbitration controller that switches operations from one device to the other in the event of an outage.
This provides ease of service and allows the operator to feel confident that the differential GPS equipment is operational at all times.
Both NAVTEX transmitters can also be remotely monitored by RS485 thanks to a remote controller that offers full control.
These devices provide monitoring capabilities using an embedded Ethernet server and a simple Ethernet connection so no additional software is acquired.
Users also find that monitoring is intuitive and simple due to a membrane keypad with which users can input controls.
Each device is also outfitted with built-in test equipment that enables users to complete troubleshooting from any location.
An LCD display on the surface of the device allows operators of NAVTEX transmitters to view test point data within a specific transmitter, while a microcontroller oversees critical parameters automatically, taking preprogrammed steps to address abnormal conditions.
The major difference between the SV1500 and SV3000 devices is the amount of RF power output, with the number after the "SV" indicating the number of watts (W) output into a fifty-Ohm load.
Power consumption for SV1500 NAVTEX transmitters is 2000 W for 1500 W RF output, while the SV3000 device uses 3750 W for 3000 W RF output.
Both devices meet applicable Federal Communications Commission (FCC) standards, so the major decision a buyer needs to make is how much W RF output is necessary.
When it comes to purchasing differential GPS equipment, buyers will find NAVTEX transmitters offer ease of service and superior usability.
