ISR Blackbox Exercise
Run simulations of the existing Millstone Hill ISR
Choose the Millstone Misa ISR in single pulse 480 microsecond mode.
Run for 24 hours during Jan. 1st using 240 seconds of integration at 90 degrees elevation.
Determine how many seconds you can reduce the integration period to and still have less than 10% error at all times at 750 km altitude.
Describe what happens when the integration period gets short (1 second).
- Repeat the second and third steps at an elevation of 4 degrees and a 2000 microsecond pulse and an altitude of 500 km..
Build a low power Millstone Hill background ISR
The idea of this exercise is to build a low power version of the Millstone zenith antenna that can make a measurement every 5 minutes. To do this, use the Simulate a new ISR tool. Use the present zenith antenna which has the following characteristics:
Freq: 440E6 Hz
Diameter: 68 m
Pulse length: 480.0E-6 seconds
0.05 duty cycle
88 degree elevation
- Latitude 42 degrees, longitude -71 degrees
Determine how low peak power you can use to get 10% error at 500 km at 5 minutes integration across the entire day on Jan 1st..
