MicroPilot

Underfill: Solder provides electrical connection to the circuit board and holds the chip onto the board. Reliability is better if you glue the Like if you like, follow for more! #MicroPilot #UAV #Autopilot #Professional chip to the board.

MicroPilot’s triple redundant autopilot installed in an early Penguin. Like if you like, follow for more! #MicroPilot #UAV #Autopilot #Professional

Thermal Expansion: As temperature changes the chip and the circuit board expand at different rates which stresses the solder joints and can lead to failure. Like if you like, follow for more! #MicroPilot #UAV #Autopilot #Professional

Retransmit commands carefully, or the wrong command might be acknowledged. Like if you like, follow for more! #MicroPilot #UAV #Autopilot #Professional

8 Bit Vs 10 Bit Joystick: Not all joysticks are created equal! If the joystick doesn’t have enough resolution, it’s hard to control a camera. Like if you like, follow for more! #MicroPilot #UAV #Autopilot #Professional

Schmitt Trigger: By using different voltages when switching from 0 to 1 versus 1 to 0, a Schmidt trigger can make messy signals nice. Like if you like, follow for more! #MicroPilot #UAV #Autopilot #Professional

We use our multi-channel GNSS simulator in conjunction with our trueHWIL to make sure our autopilot software correctly handles the many GNSS idiosyncrasies. Like if you like, follow for more! #MicroPilot #UAV #Autopilot #Professional

De-crab is a maneuver used to align the aircraft's wheels with the runway just before touchdown. Like if you like, follow for more! #MicroPilot #UAV #Autopilot #Professional

Liftoff from one of our runways! Our flight test area is right outside our office, so we fly any time we want. Like if you like, follow for more! #MicroPilot #UAV #Autopilot #Professional

Pressure Error vs. Speed Error: At low speeds, small errors measuring pressure cause large airspeed errors. These errors diminish quickly as airspeed increases. Like if you like, follow for more! #MicroPilot #UAV #Autopilot #Professional

We test fly our autopilots right outside our building. A nice view of both our runways. Like if you like, follow for more! #MicroPilot #UAV #Autopilot #Professional

Nyquist Rate: Processors must sample a signal before they can use the signal. Knowing the maximum frequency of a signal is key to knowing how fast it must be sampled. Like if you like, follow for more! #MicroPilot #UAV #Autopilot #Professional

Calibration eliminates variation between sensors. MicroPilot uses a two-axis temperature chamber to calibrate and test its inertial sensors. Like if you like, follow for more! #MicroPilot #UAV #Autopilot #Professional

Hysteresis: Hysteresis is a source of measurement error that changes with past measurements Like if you like, follow for more! #MicroPilot #UAV #Autopilot #Professional

Aliasing: A digital computer can only work with analog signals by sampling them periodically. If you don’t filter the signal properly before it is sampled, you may have unexpected results. Like if you like, follow for more! #MicroPilot #UAV #Autopilot #Professional

Our flight test area is right outside our office, so we fly any time we want. Like if you like, follow for more! #MicroPilot #UAV #Autopilot #Professional

Low pass filter: A low pass filter is described by two parameters: -3 dB point (or cut-off frequency) and order. Like if you like, follow for more! #MicroPilot #UAV #Autopilot #Professional

The safety analysis creates requirements for a UAV. These requirements result in the creation of lower-level requirements for the various parts of the UAV (i.e., GCS, autopilot etc.) Like if you like, follow for more! #MicroPilot #UAV #Autopilot #Professional

Gravity’s effect on Asymmetric Clipping: Gravity makes the effect of Asymmetric clipping on accelerometers much worse. Like if you like, follow for more! #MicroPilot #UAV #Autopilot #Professional

Non-Linear response: Vibration, combined with a non-linear response of accelerators, results in a DC offset or bias. Like if you like, follow for more! #MicroPilot #UAV #Autopilot #Professional
