About tracking device - various types of GPS receivers
In this highly competitive world, any business can survive and grow only if it’s ready to accept changes and adapt to new technology. Online vehicle tracking is one such innovative service that will add a lot of value to your services. GPS tracking provides numerous benefits that help increase revenue. These include reduced fuel costs, lower insurance premiums, increased productivity, improved dispatching, and back office efficiencies. For the driver, all these benefits add to job security with a financially stable company. Saving money on fuel alone over the course of the year can potentially equal to an entire salary for one employee. Increased revenue can also be forwarded to employees in the form of bonuses. Rewards based on data collected from GPS tracking can boost morale and help gain acceptance of the system. Employees should know that while it may be new to your business, personal tracking device is rapidly becoming the industry standard for any business with a fleet of vehicles. Your competitors are already using GPS to maximize profitability. By not embracing this technology, you would be putting your business and employees at risk.
GPS technology is continually evolving with a large variety of GPS receivers being developed for many types of applications. A electronic tracking devices can be combined with other electronic devices into one package. Units are available that combine a receiver with an electronic compass, pressure altimeter, wireless phone, or emergency transmitter. Of most interest to wilderness navigators, are lightweight units that can quickly acquire a position fix without consuming too much battery power.
Signal gathering techniques
The method that a GPS Tracking Device uses to gather and process satellite signals governs how quickly and accurately it can obtain a position fix.
Sequential receiver
A sequential receiver uses one channel to gather all the data it needs from one satellite, then switches to the next satellite and so on until it has enough information for a position fix. This type of receiver can get stuck on one satellite if it’s unable to obtain a complete signal. The unit is cheap and doesn’t use much battery power. However, it is often slow getting a position fix and can quickly lose the fix if a satellite disappears from view.
Multiplexing receiver
Multiplexing receivers use one channel to gather partial data from one satellite for a short time interval, then switch to the next satellite for the same time interval, and so on until there is enough information for a position fix. Multiplexing receivers don’t get stuck on one satellite and perform somewhat better than sequential receivers.
Parallel channel receiver
Parallel channel receivers use several separate channels that simultaneously gather signals. Each channel gathers signals from one satellite only. Generally, this type of receiver is faster at getting a position fix, less likely to lose one, and the best type for obtaining position readings under tree cover. The added circuitry uses more battery power. Parallel channel receivers have largely made sequential, multiplexing, and hybrid receivers obsolete.
Hybrid receiver
Hybrid receivers have several separate channels, some of which may be dedicated to a single satellite and some multiplexing or sequential. These types of receivers have intermediate performances.
Dual frequency receiver
Dual frequency receivers are mainly used for surveying or military purposes. They make use of a second carrier frequency transmitted by the GPS satellites to reduce errors caused by atmospheric conditions. These errors can be calculated directly because different frequencies are slowed down by different amounts in the atmosphere. Dual frequency receivers are much more accurate than standard receivers but are heavier and more expensive.
