Rocket Management System
Subassembly Frame
• Max. thickness: 0.7”
• Frame bulk thickness: 0.25”
• Symmetrical
• Fillets to reduce stress concentrations
• Machined from a single piece of material
• Canard mechanism block oriented at 45 degrees
• RS-232 digital serial interface (12 V DB9)
• Transfer data rates from 300bps to 115200bps
• Standard 9600bps baud rate
• Data format based on target data:
• Current position and elevation
• Target position and elevation
• Current speed
• Guidance module returns “target acquired” signal
Female/Male Interfaces
• Aluminum construction
• Acme stub nose threads (pitch = 6)
• Depth of interface fitment = 0.5 in.
• Secured with press fit pull out pins
Canard
IMU
• Honeywell HG1930 Gun-Hard MEMS IMU
• Serial I/O
• RS422 interface
• Synchronous or Asynchronous
• 5VDC power supply
• Provides linear and angular acceleration ΔV(x,y,z) ω(θ,φ,ψ)
• 9600bps data transfer rate
Development of a precision guidance avionics module for the Hydra 70 rocket
missile.
• M261 MPSM warhead
• M261 19-round launch platform
• MK 66 rocket motor
 Module will have built in IMU and GPS guidance systems
 Module will contain 4 canards actuated by servo motors that will perform flight
adjustments
