Decision: We're using 802.11b for the September flight. We're not using power amplification. We are going to use antenna amplification. If Larry gets an FCC waiver, then we'll go way overboard with antenna amplification ;).
But: We desperately need someone to design cylindrical patch antennas for us!.
- PC104 586 - $350 -> w/ SRAM and CHIPDISK $600
- PC104 PCMCIA - ~ $120
- PC104 CAN - ~ $200
- No PIC18F458 Yet (ack!)
- Alternative? PIC16F873 + SJA1000 CAN
- Motorola DSP56F8xx?
At the Launch Tower:
LB: Launch Box (battery, key interlock, toggleswitch -> PLEASE PLACE AT LEAST 12ft FROM THE LT). LTM: Launch Tower Microcontroller (Relays,relay). LTC: Launch Tower Computer (Laptop with 802.11b & YAGI, soundcard, loudspeaker).
At the Launch Control Module:
Telemetry Computer (laptop w/802.11b & YAGI (Aimed? Or static?)). Launch Computer (laptop w/802.11b & YAGI).
Monitors in the LCM: ATV, Telemetry, Launch Computer
