Gyro drift rates of xx deg/hour (with xx being a 2 or 3-digit\nnumber) are the norm. They are great for aiding GPS when a vehicle is in\na tunnel, or firing air bags on rapid decceleration, but they don't do\nmuch for our needs for inertial nav.\n\nIMHO, It might be useful to fly one to measure the 3-axis kick vector\nduring a motor burn, and/or perhaps for helping to measure the\ninstantaneous angular velocity changes when magnetorquing.\n\nTom\n\n", "attachments": [] }
