Q

What makes a DAGR (defensive advanced GPS reciever) jam-resitaant compared to commercial receivers

A

Encryption; Receives 2 Freqs L1 and L2; (CA to make the shake for P(Y))

Q

In order to utilize the P(Y) code what must the receiver have?

A
  1. Receiver must be turned on to have C/A prior to entering the ‘jamming zone’
  2. Batteries must be full…don’t want to drop ‘key’
  3. C/A will enable P(Y) which is what will encrypt the DAGR

Q

What factor determines DOP? (Dilution of Precision)

A

Geometry of Satellite in View, it is the angle of the satellites in relation to one another.

too close and there may be issues…

High Geometry = far apart in sky and the DOP value is LOW…in the business! farther apart than a bad dop situation

Weak Geometry = close in sky and the DOP value is HIGH…no bueno

Q

What is Multipathing?

A

This is when a signal bounces off a ‘canyon wall’ and can cause an error or delay…

for example, signal is sent from SAT to GROUND, bounces off the canyon walls, produces a delay by 1 nanosecond…my DAGR on the JCR is not reporting my location off by 1 foot…

Q

From a DEPENDANCE standpoint, List 3 reasons the US army is concerned about GPS jammers

A
  1. GPS is the default PNT system for many of us

Q

From a SUSCEPTIBILITY standpoint, List 3 reasons the US army is concerned about GPS jammers

A
  1. Weak GPS signal (40 watts) mean its susceptible to jamming with little to no power from a jamming transmitter
  2. jamming tech and cost is inexpensive
  3. jamming systems can appear anywhere w/o warning (think cigarette box size
