Arming Checklist

questa checklist è divisa in una sezione prima della rampa (da fare in hangar o in tenda) e una da fare a veicolo su rampa.

OPERAZIONI PRE RAMPA

Prima di muovere e montare il veicolo su rampa.

E' fondamentale dimostrare che il GPS ha già acquisito un lock nel periodo immediatamente precedente al lancio (~ 1 giorno). Nel momento in cui il GPS viene acceso da un lungo periodo senza potenza dovra scaricare i dati orbitali necessari a completare le varie operazioni. E' importante quindi accenderlo e aspettare che faccia almeno un lock per dimostrare che il componente abbia scaricato i dati GNSS.Al fine di ricordarsi l'ultimo track il GPS è accompagnato da una mini batteria. Questa batteria, per motivi tecnici, è estremamente lenta a caricarsi, quindi può essere utile lasciarla in carica (connettendo la scheda a un computer) per diverse ore (e.g. un'interna notte). Valori di reference batteria:

2.7 Volts ~ Scarica

3.0 Volts ~ Carica

Ricordarsi di fare la stessa procedura sia per il GPS che verrà montato che per il GPS di backup, in caso di problemi, oltre alle schede COTS. I COTS potrebbero non avere una batteria integrata o potrebbe non essere banale controllarne la carica.

 [ ]  connect [MAIN] SRAD to battery
 [ ]  wait for handshake packet from the SRAD telemetry
 [ ]  wait for the first good GPS packet from the SRAD telemetry
 [ ]  disconnect [MAIN] SRAD from battery
  
 [ ]  connect [BACKUP] SRAD to battery
 [ ]  wait for handshake packet from the SRAD telemetry
 [ ]  wait for the first good GPS packet from the SRAD telemetry
 [ ]  disconnect [BACKUP] SRAD from battery
  
 [ ]  connect featherweigth tracker to battery
 [ ]  wait for handshake packet from the featherweigth telemetry
 [ ]  wait for the first good GPS packet from the featherweigth telemetry
 [ ]  disconnect featherweigth tracker from battery
  
 [ ]  connect Vega to battery
 [ ]  wait for handshake packet from the Vega telemetry
 [ ]  wait for the first good GPS packet from the Vega telemetry
 [ ]  disconnect Vega from battery

OPERAZIONI IN RAMPA

Dopo aver montanto il veicolo in rampa.

E' importante garantire la sicurezza del personale in ramp-duty. Parte del team sarà sotto rampa fino ad armaggio mentre il resto rimane alla base per comunicare e operare la

COMMUNICATE ALL STEP TROUGH RADIO

 [ ]  Ramp-duty officer has one of the launch keys
 [ ]  Open Avionics Bay
 [ ]  connect SRAD to battery
 [ ]  connect Vega to battery
 [ ]  connect Blue Raven to battery
 [ ]  connect SRAD tracker to battery
 [ ]  connect featherweigth tracker to battery
 [ ]  start the onboard camera
 [ ]  wait for handshake packet from the SRAD telemetry
 [ ]  wait for the first good GPS packet from the SRAD telemetry
 [ ]  wait for handshake packet form featherweigth tracker
 [ ]  wait for good parameters from the SRAD telemetry 
 [ ]  wait for the first good GPS packet from the featherweigth tracker
 [ ]  arm the SRAD board
 [ ]  arm the Vega board
 [ ]  arm the Blue Raven board
 [[ ]]  check all systems online: 
        [ ] check Vega LED or Buzzer		
        [ ] check Blueraven on bluetooth	 	
        [ ] check SRAD LED or Buzzer
 [ ]  close the Avionics bay
 [ ]  arm the Blue Raven trough the app
 [ ]  vacate the area
 [ ]  arm the SRAD board via radio
 [ ]  Hand over Ignition key
