Short Description
In ski jumping, low repetition rates of jumps limit effectiveness of training. Thus, increasing learning rate within every single jump is key to success. A critical element of athlete training is motor learning, which has been shown to be accelerated using feedback methods. Today, coach’s training feedback is mainly oral and based on recorded video data. Video data provides good insight into the entire jump, however translating video information into actual motor control is difficult
To improve current feedback methods, we want to develop an in-action system that converts sensor node data into simple yet motor-transferable information. To do this, data must be transmitted between onbody sensor nodes as well as between a sensor node master and the coaching tower. This requires reliable wireless communication with sufficient bandwidth and range.

Detailed Task Description
The main objective of this work is to implement and test a reliable Bluetooth Low Energy Coded PHY radio communication between an existing sensor node and a gateway. Field measurements (also with real ski jumpers) shall demonstrate the performance of the developed system. According to the level of the student and the chosen thesis type (BT/ST) the work will include some or all following tasks:
Goals
Characterization
- Characterization of data transmission quality and identification of losses using BLE coded PHY in various scenarious
- with increasing distance between source and target
- with high velocity differences between source and target.
- Using synthetic and/or real sensor data
- In laboratory like conditions and infield on a skijumping hill
Firmware Development
- Implement the BLE coded phy stack on an existing multisensor system for ski-jumping
Field Test
- The Validation procedure will require testing of the system in real world conditions on a ski jump.
