Question

there are two methods for determining the range from the SV to the REC in GPS. Code (C/A and P) and waves (L1 and L2) discuss two elements of GPS signals as they relate to each method. choose from the list of elements shown below.1.determination of time,2. Atmospheric errors3. correlation of signal at REC4. what is actually measured at the REC5. Accuracyplease follow these steps after choosing the two elements1. a header with the element you will discuss2. one short paragraph on the element to be discussed for example what is the element. might be just 2 to 3 sentences3. one paragraph explaining how the elements effect s waves and how it effects codes.i am looking for general effects not alot of technical details.

Determination of time; and Atmospheric errors in GPS signals
i) GPS-Time is a continuous measurement of time from an epoch started at January 6, 
1980 at midnight (0 hours 0 minutes 0 seconds ) Universal Time Coordinated (UTC). 
GPS-Time does not introduce leap seconds and so is ahead of UTC by an integer 
number of seconds. GPS Time is steered by the Master Control site to be within one 
microsecond (less leap second) of UTC.
ii) GPS atmospheric errors include delay of the GPS carrier signals as they pass 
through the layer of charged ions and free electrons known as the ionosphere. 
Varying in density and thickness as it rises and falls (50 to 500 kilometers) due to 
solar pressure and geomagnetic effects, the ionosphere can delay the GPS signals by 
as much as 300 nanoseconds (100 meters). GPS signal delays through the troposphere
