Figure Out Your Lowrance GPS Unit For Best Effectiveness...
By: Edwardo Mascasas -
Lowrance GPS units are one of the top models available to
consumers. Lowrance GPS products are GPS receivers. These products
gather data from a satellite and display your location on a
screen.
GPS is sweeping the market, which is why it's good to go with a
brand that has established itself as a leader in GPS technology
since people are after the good quality of products.
There are Lowrance units that are specific to aviation needs,
marine navigation needs, automotive applications, and those that
were designed for on-land adventures.
Lowrance Global Positioning system uses satellite ranging to
triangulate your position. In other words, the GPS unit simply
measures the travel time of the signals transmitted from the
satellites, then multiplies them by the speed of light to determine
exactly how far the unit is from every satellite it's sampling. GPS
works 24 hours a day, anywhere in the world and is not affected by
clouds, storms or weather.
By locking onto the signals from a minimum of three different
satellites, a GPS receiver can calculate a 2D (two-dimensional)
positional fix, consisting of your latitude and longitude. By
locking onto a fourth satellite, the GPS can compute a 3D
(three-dimensional) fix, calculating your altitude as well as your
latitude/longitude position.
In order to do this Lowrance uses a 12 parallel-channel receiver in
all of its current products. Three of the channels lock on to
satellites for triangulation. Another channel locks on to a fourth
satellite for 3D navigation, which lets the unit calculate altitude
in addition to latitude and longitude.
These four channels continuously and simultaneously track the four
satellites in the best geometrical positions relative to you. The
additional eight channels track all other visible satellites, then
add this data to the data from the original four satellites. The
unit then over-resolves a solution, creating an accuracy-enhanced
reading. The additional channels also ensure reliable, continuous
and uninterrupted navigation, even in adverse conditions such as
valleys or dense woods.
Furthermore, the life of the battery in your handheld GPS unit
depends on a number of factors. First and foremost is the quality
of the batteries you are using. Be sure to select a high quality
alkaline battery. Using the Power Save feature whenever possible
and keeping the backlight panel off when not needed will assure
maximum battery life. Depending on the unit you have, your average
battery life will be between 8 and 20 hours.
One sample product of a Lowrance receiver is the Lowrance
Differential Beacon Receiver. It is completely sealed and
waterproof to withstand even the harshest of environmental
conditions, and is backed by our Full One-Year Warranty. The result
is unmatched accuracy for your Lowrance differential-ready GPS
receiver.
Signals from land-based DGPS stations are used to correct for the
effects of SA and other accuracy-degrading limitations. These DGPS
stations, operated by the U.S. Coast Guard or similar agencies
around the world, offer free DGPS corrections broadcast on
283.5-325 kHz. The Lowrance DGPS Beacon Receiver outputs RTCM
SC-104 format corrections to any DGPS-ready GPS receiver.
Lowrance produces many software and manuals to enhance the GPS
experience. It is important that users new to GPS read the manual
for whatever unit they choose to buy, regardless of brand. As
consumers, there are lots of functions you want to figure out.
