 ===== Aims =====
   * To repeat the success of PicoAtlas IX
-  * Attempt uplink
   * Launch early morning to look at how timing affects float period
 ===== Improvements =====
-  * Switch to RF22 library to allow us to Rx and Tx
   * Add more $$$$$ after radio reset to avoid problems decoding the first string
-  * Add uplink window every 20 strings before radio is reset
 ===== Launch Conditions =====

   * Flight path keeps it within radio rx range for 24hours
+===== Launch =====
+  * Easy launch, filled balloon and released
+  * Perfect weather, <5mph winds, hot day, clear skies
+  * GPS seemed a bit noisy may have been due to desensitised + power saving mode
+  * Started floating around 5km but kept climbing very slowly, sprung a leak and descended over Norfolk
+  * Not yet recovered.
+===== Flight Data =====
+{{:projects:picoatlas:mappicox.png|}}
+{{:projects:picoatlas:altpicox.png|}}
+  * Ascent rate = 0.9m/s
+===== Conclusions =====
+  * Harder to float the balloon during the day (however if you manage it it should last for a long time as you'd get a whole day, then night and then potentially another day)
+  * The flight code works well, it was nice to have battery data
+  * Need to have a way of exposing the antenna without it being desensitised
