-## Improvement Goals for Spring
+## Goals for Launch
### Major Initiatives
-#### "RocketNet" Data and Power Distribution Board (ECE Capstone course)
-
- - STM32-controlled power switches
- - 8 port 100Mbps Ethernet switch
- - Umbilical interface and battery charger
#### Olimex STM32-E407 based IMU with Ethernet
+We have an [[Analog Devices ADIS 6 axis + magnetometer IMU|avionics/av3-imu]] that needs integration into our flight computer. We have opted to use an STM32 ARM based microcontroller to handle low level communication with the sensor, while reporting it's values over Ethernet to the FC.
+
+
#### Olimex STM32-E407 based roll control with Ethernet
+We want to use the same STM32 architecture to do other low level work, in this case send updates to the roll control servo. This board does also doubles as the hardware launch detect (using a shorted tether).
+
+
#### LTC API
- - And Ground software
- - No gel cel for ignition (liPo instead)
+Over the last year we rebuilt our [[Launch Tower Computer (LTC)|GroundTeamHome/launch_tower_v3/]]. This computer serves as the link to the rocket when it's on the pad, providing power and communication as well as safely controlling the ignition. This also meant rebuilding the software to talk to it.
+
+
+#### Roll Control on the main Flight Computer
+
+We validated Roll Control on our October 2010 launch. But this was using a one-off, completely embedded solution. We very much would like to fly the same algorithm using our new flight computer framework, Ethernet communication, etc.
+
-#### Roll Control on FC
+#### Flight Computer Framework
-#### FC Rocket Ready based on real contstraints
+This winter/spring CS Capstone team built a [Flight Computer Framework](https://github.com/psas/elderberry). This allows us to write modules in c and then define the connections and program flow between them using simple configuration files. The framework then handles setting up the build targets, events and callbacks for the computer. This is the flight test using the new code.
- -
-#### RocketTracks
+#### FC Rocket Ready based on real constraints
- - Stretch goal?
+The new LTC has an additional level of safety on the firing sequence. The flight computer _must_ assert a line high to let a relay close and allow the rocket to be fired. This lets us check for conditions on the rocket (GPS lock, sane sensors, etc.) and automatically safe the launch circuitry if something goes wrong.
-#### Update Camera
+#### Updated Camera
-#### 3D Printed Connectors
+We have a new HD camera pointed out the side of the rocket, as well as a new 3D printed shroud for the downward facing camera.
-### Technical Nitpicks
+#### 360 Camera Module
+
+A special payload is flying on this launch. A 360&deg; camera module made up of 5 GoPro's will sit just above the roll control module and will be stitched after flight into a singular, extreme HD full view of the flight!
+
+
+#### 3D Printed Net Connectors
+
+One of the small innovations on this launch are small, locking connectors for the ethernet and power that are partly COTS and partly 3D printed.
- - More thoroughly test GPS
- - Ground systems test (antennas, wifi)
- - Integration test
- - FCF test
