Question
Chapter 13, Problem 13.1P
To determine
The names of the two new civilian codes added to the modernized satellites.
Expert Solution & Answer
Answer to Problem 13.1P
The two new civilian codes added to modernized satellites are:
L2C codeandL5 code
Explanation of Solution
Given Information:
Earlier only C/A and P codes were used to modulate the GPS signals. L1 frequency was modulated with C/A and P codes while L2 frequency was modulated with only P codes.
Today in the modern satellites L2 frequency is modulated with a second code called the L2C code and its P-code is replaced with a new military code known as M-code.
Also in 1999, the Interagency GPS Executive Board (IGEB) added a third civilian signal known as the L5 which has both civilian code and a codeless component.
So today the two new civilian codes added to modernized satellites are:
- L2C code
- L5 code

As discussed in class, an alternative and frequent way to model the demand is doing it in 4 steps: Generation/Attraction, Distribution, Mode choice, and Route choice. In the generation/attraction step, we estimate the number of trips that depart and arrive from each zone, in a similar way as we studied generation in the lectures. The idea of the distribution step is, taking the generation and attraction numbers as known, estimate the number of people going from each zone to each zone. Let's be precise: Consider that you know O₂ for every zone i, representing the number of users that have i as their origin. Similarly, you know Dj, representing the number of users that have j as their destination. We want to estimate Mij, i.e., the number of users going from i to j. The matrix Marrow_forward= a2+ Assume an origin is connected to a destination with two routes. Assume the travel time of each route has a linear relationship with the traffic flow on the route (t₁ = α₁ + b₁x₁ ; t₂ b2x2). Determine under what condition (e.g. a relationship among the parameters of the performance functions) tolling cannot reduce the total travel time of the two routes.arrow_forward
