Is the microAlt capable of operation through Mach?
No provision is made for working around the pressure disruptions encountered as a rocket s airframe passes from subsonic to supersonic flight. Therefore the recovery/ejection features are not recommended for use in vehicles in this performance category, though the data logging feature would likely provide some interesting data. The microAlt is intended as a low-cost general use altimeter, and its tiny microprocessor simply doesn t have enough I/O pins to support additional features like mach holdoff delays. A slightly larger, more expensive unit will be available soon with many more features like mach-safe operation, accelerometer, larger data memory, etc.
