Question

What are the methods for ascertaining the integrity of a receiver in GPS?

Answer #1

7. Which of the following is the most significant source of
error in position from GPS signals?
A. Atmospheric effects
B. The GPS satellite clock
C. Sunshine impacting the receiver
D. Clouds or Rain

1. compute the orbital radius and height above the earth for a
GPS satellite based on its orbital period of 12 hours.
2. Estimate the ground footprint, in square miles, of a single
satellite using simple trigonometry to determine what percentage of
the earth’s surface can be “seen” from a single satellite.
3. Continue this “back of the envelope” analysis to estimate the
total number of GPS satellites that are needed in order for a GPS
receiver to have visibility...

The costs to a store for two models of Global Positioning System
(GPS) receivers are $80 and $100. The $80 model yields a profit of
$25 and the $100 model yields a profit of $30. Market tests and
available resources determined the constraints below.
a.) The merchant estimates that the total monthly demand will
not exceed 200 units.
b.) The merchant does not want to invest more than $18,000 in
GPS receiver inventory.
Formulate the math model and solve it,...

personal health and exercise, including pedometers and GPS
technology. There are also a wide variety of cell phone health apps
that can assist in tracking distance run, heart rate, and calorie
intake, among other health measures. Conduct your own search to
identify a health app available on cell phone.

Is that possible, for any antenna, to be used as a
receiver and transmitter? What is the point of that?

GPS
satellites orbit the earth with a speed of 14000 km/hr relative to
fixed positions on earth. Is this a relativistic speed? By how much
do clocks on the satellites lag behind clocks on earth per day? If
the timing of signals from the satellites received by an earth
receiver must have 20 ns precision to determine position within 5
meters, can special relativity be ignored? How long before the
difference in time measurements would exceed the required
precision?

What is the difference between body composition reference
methods and anthropometric field methods?
Both methods capture the same data
Anthropometric field methods can be used as the gold standard
for true body composition while reference methods are compared to
that gold standard
Reference methods are biologically-based, objective measures
while field measures are mostly based on self-reported data
collected in the field
Anthropometric measures are typically more expensive than
reference methods
All of the following are advantages of CT and MRI...
