  4. This is your calculator 1965 -- Texas Instruments (USA) begins work on a hand-held calculator, code named "Cal-Tech." It was to be developed as a prototype to show the potential of TI's recently-developed integrated circuits (which were not selling as well as they had hoped). The "Cal-Tech" featured four function calculations (+, -, x, /) and used a thermal paper tape printout. :

  5. SATURN I Block II Analog Flight Control Computer • The analog Flight Control Computer was manufactured under subcontract to IBM by COMMUNICATIONS ELECTRONICS CORP in 1962 for the Marshall Space Flight Center (MSFC) • Operated in conjunction with the Launch Vehicle Digital Computer • The flight computer, installed within the Instrument Unit (IU) controlled extension/retraction of each of 12 gimbal servo-actuators • The Flight Control Computer analyzed input resulting from several forces acting on the vehicle such as engine thrust, wind, gravity and internal vehicle flexing and bending • The signals, measured and inputed from the stable platform, rate signals from rate gyros or lead networks, angle-of-attack information from body-fixed accelerometers and other sensors, are shaped, given a weighting function, and combined with program data in several servo amplifiers • The resultant amplified outputs drive the servo actuators which gimbal the engines to provide nozzle deflective thrust vector control for the S-I and S-IV stages.

  6. The Apollo Guidance Computer • Clock-speed • The AGC had a clock-speed of 2.048 Mhz • The modern computer’s clock speed on the average of 2.4 Ghz • RAM • The AGC had a RAM of 4 Kb • The modern computer standard ram is 2000 kb • ROM • The AGC has a ROM of 32 Kb • The modern computer standard main rom (the hard disk) usually at 160+GB • Software Language • The AGC was programmed by the “Assembly Language” • The Microsoft Windows is programmed by “BASIC” • REGISTERS • The AGC had a central registers of 16-bits • The modern computer CPU registers are now 64-bits

  7. Steps to the Moon Example Altair Computer Needs Orion Vehicle Management Computer Apollo Analog Flight Computer

  8. Avionics Panel Discussion • Compare/Contrast Apollo to Constellation. Similarities, differences both mission and technologies. • Training an intelligent simulator and Robotic Landing Control System (RLCS) • Pilot/astronaut input to artificial intelligence for lunar landing. • Testing an intelligent simulator and RLCS with manual vs. robotic control of an LLTV.
