Avionics and Communications Current Task list

Overview of What Needs to Be Done (WNTBD)

Old old old old stuff

Replace LTR ignition and RRR relay with 12A relays and figure out why the LTR relay died.
Review CurrentCheckList and CurrentBringList
Pass pre-defined integration tests
Redo the LTC igniter cable to extend 50' from LT using two 25' extension cables with igniter alligator clips on one end and a female banana receptacle for the shorting on the other (protected by a box)
Sanity check avionics module hardware, including compactflash card strapdown, wire strainrelief and euroterminal block tightness
Kapton antennas at seams with 1" kapton tape
Copper tape 2m receiver box, locktight, decide on third nut, strain relief ribbon cable
APS node firmware update (to sync to latest code, and for better low-current readout, and should never kill batteries if not armed.)

Double sticky foam tape a box of fuses to the inside of the LTC
Mark which hole is correct for upper launch lug and better marking module connections
Prototype ground suitcase
Recovery node shouldn't ever kill the battery
GPS node firmware update (so it too can go into "silent" mode)

Task priorities:

You can find previously completed tasks in the history of this page.

Priority	Status	Who	Task

Priority	Status	Who	Task
3		A/T	Re-think plates for new PPC cpu. Improve sliding, etc.

Priority	Who	Task
2	A/T	Better battery charging algorithm using current sensing
2	ADG	Update firmware: Sync to latest code, and for better low-current readout, and should never kill batteries if not armed.
3	ADG	Firmware for Batt temp thermistor (charging cutoff)

Priority	Status	Who	Task

Priority	Status	Who	Task
1		ADG	Kapton antennas using 1" tape along seams

Priority	Status	Who	Task
2	blocked		Start PPC mechanical design

Priority	Status	Who	Task
2		ADG	Update GPS firmware
3		A/T	Go to mg5001

Priority	Status	Who	Task
2		ADG	Calibrate calibrate calibrate!

Priority	Who	Task
1	?	Fix badly frayed power cord on solar array, prevent recurrence
2		Add Amp-Hour meter to umbilical
2	?	Add battery voltage, PV voltage, and internal box temperature sensors and messages
3	TH	Dedust and paint 3/4 inch plywood antenna bases
3	A	Add the 2mm LED jumpter back on the LTC

Priority	Who	Task
1	T	Copper tape 2m receiver box, locktight, decide on third nut, strain releif ribbon cable
1	ADG	The recovery node is not reseting the timers (or something) when taken out of ARMED mode. (This is both a bug and an architectural failure.) The symptom is "**" for the drogue timers on the 2nd and subsequent test runs. The main timers may also be wrong but are out of range and can't be read ("????" -- dare to use a decimal point)
2	ADG	Prevent battery death when NOT ARMED
2	ADG	Fix weird charging messages
2	ADG	Fix lack of battery current in battery message
2	ADG	implement quiet mode, if not already done
2	ADG	Sync code to latest APS firmware so that emergency powerdown works

Priority	Status	Who	Task
1		A/T	Replace RRR relay with a high capacity version.
3		A/T	Replace RRR relay LED with a clear, high efficiency red LED.

Priority	Who	Task
1	A/T	Remove, diagnose and replace ignition relay
2		New LTC igniter lights
3	A/T	Replace RRR relay LED with a clear, high efficiency red LED.
3	?	Make LT relay SPDT sense contacts inputs on PIC
