The gps device in an automobile uses which communication channel

The communication channel is fm.

the global positioning system (gps) requires some external receiver to encode the satellite broadcasts with time corrections, data on ephemeris (the orbits of satellites), and earth-based information about earth's geometrical structure by using the doppler effect. this new signal is then broadcast on either medium wave (mw) or very high frequency (vhf, see fm band). your car radio can be tuned to these signals; it will recognize them as a weak but stable carrier that you can adjust the volume up or down for clear reception. most gps receivers come already working in conjunction with an internal antenna, but there are also many aftermarket antennas available for purchase if necessary.

the gps device in an automobile uses which communication channel?

a) satellite
b) microwave
c) radio frequency
d) infrared

the gps device in an automobile uses a communication channel known as the l1 frequency, which is both very accurate and has lots of bandwidth.

the l1 frequency is a 1.0 gigahertz signal that utilizes the output from about twenty-four different satellites to provide global coverage. this type of system is called carrier phase differential gps because it relies on a tracking signal transmitted by each satellite which can be tracked separately since they drift relative to one another over time. the problem with this system is that its accuracy only reaches between 10m and 20m because of ionospheric distortion effects which also cause multipath problems for signals reflected off surfaces including buildings, trees, and hillsides. animals can also interfere with signals if they

the gps device in an automobile uses which communication channel?

the gps system in an automobile uses the navstar series of satellites, which are owned and operated by the u.s. department of defense.

utilizing six satellites orbiting at medium altitude (~11,000 miles), this satellite-based system is able to fix a vehicle's position to within 50 meters anywhere on earth – reliably enough that most cars could count on accurate information for almost any journey they undertake in old world europe, africa or north america.

gps is a strong partner in the evolution of the automated vehicle.

gps is a powerful asset when delivering an automated vehicle to its destination. it's a separate channel but in most cars with integrated navigation systems, it's combined with the multimedia hub and in many cars with satellite radio or idrive, music can be streamed or stored on flash drives which eliminates any need for wires attached to your cell phone. the devices have evolved so that features like navigation, entertainment, cruise control can all work together at once without interrupting each other by default; they also detect anything to make you aware of less than ideal driving conditions like accidents ahead (thereby alerting you before entering an accident zone), back-up warnings if needed (

the gps device in an automobile uses which communication channel?

it uses satellites.

gps stands for global positioning system, so it relies on high precision timing signals generated by a network of thirty-four satellites orbiting the earth. the satellites broadcast two low power radio signals at l1 and l2 frequencies respectively. gps receivers can use these satellite transmissions to calculate the receiver's own position, accurately within tens of meters in all weather conditions, anywhere on or near the earth where there is an unobstructed line of sight to four or more satellites with good reception. the distance between “time ticks” is then counted for an accurate ~~timeline~~ time measurement that can be used to ~~~~pinpoint ~~~~the receiver's location on earth ~~to within fractions of a second–

the gps device in an automobile uses which communication channel?

the gps device in an automobile uses a l1 frequency, which is a specific range of electromagnetic waves on the electromagnetic spectrum.

there are many different bands on the electromagnetic spectrum, some with limited bandwidth and some with wide bandwidth. a band that has limited bandwidth carries less information than a band that has wide bandwidth because it must be encoded into pulses. in order to represent one bit of binary data using a single pulse on this narrowband channel, the length of the pulse cannot exceed 0.3 microseconds (a duration greater than 10 microseconds will most likely destroy its utility for this purpose). but if we send these same bits out over a broadband l1 frequency instead, we can use arbitrarily long pulses and each additional bit will add
