I recently had an episode where my drone would not arm. It was not able to obtain a GPS fix.

I'm running:

ArduCopter V3.2.1 (36b405fb)

PX4: ce602658 NuttX: 475b8c15

PX4v2 00360029 32334711 31363032

Frame: OCTA_QUAD

I suspect I accidentally changed some parameters. I compared all of my current parameters (from the wouldn't-arm episode) to parameters from my last successful flight data log.

I found discrepancies in a number of parameters and would like to investigate. I can't find any information on the following parameters - not on the full parameter list in Mission Planner, nor the APM copter wiki "full" parameters list here:

GND_ABS_PRESSURE

INS_GYR2OFFS_X, Y, & Z

INS_GYROFFS_X, Y, & Z

MIS_TOTAL

POSCON_THR_HOVER

SR0_PARAMS

SR1_EXT_STAT

SR1_EXTRA1, 2, & 3

SR1_PARAMS

SR1_POSITION

SR1_RAW_CTRL

SR1_RAW_SENS

SR1_RC_CHAN

Any help or hints would be greatly appreciated. Any direction to a resource with complete parameter list, descriptions, and applicable range of settings would be fantastic :)
