BioRowTel® data acquisition system

The system, which can measure everything in rowing!

Compare to other telemetry systems, our BioRowTel system is not "turn key” product and require qualified personnel (usually with sport-science qualification) and some learning curve of calibration and data processing.

In return, BioRowTel is the most flexible, accurate, can measure more variables in as a standard (e.g. vertical oar angle, segments velocities) and opened to any new transducers. It allows to collect data through up to 128 channels at 25, 50 and 100Hz with 14 bit resolution.

BioRowTel is an ideal solution for elite rowers in National teams and researchers in universities.


Standard components of BioRowTel system

The main electronic unit Master contains:

the main processor, 2 Gb memory (enough for more than 100 hours), 5 Hz GPS receiver, 3D accelerometer and 2D gyro, RS232 output, radio modem, Li-Ion battery and 12 external input channels


Up to 8 additional Slave units can be connected to the Master in a chain. Each Slave unit contains:

processor, analogue input for 8 or 16 channels, two impulse inputs (heart rate or impeller), RS485 connection tot the Master, RS232 output, "traffic lights" immediate feedback.

Two-dimensional (2D) oar angle sensor measures position of the oar shaft in horizontal and vertical planes. This allows to define the track of the blade relative to water level and hence catch and release slips and effective angles.

The force sensor measures the force applied to the oar handle by means of detection of the shaft flex. Unique calibration method takes less than a minute to calibrate each oar. This allows very accurate calculation of rowing power, which does not affected by the point of force application on the handle. The sensor is small, light and can be used on both sculling and sweep oars.


Position sensors of the seat and shoulders allow to derive their velocities and power input into total rowing power, which makes it possible to define rowing style and conduct in-depth analysis of the technique.

Wind speed and direction sensor measures effect of wind on the boat speed in a real time. This allows to determine prognostic boat speed for a calm conditions and accurately compare performance of the crew(s) in a various weather conditions.


Software package implements a unique averaging algorithms, which allow unambiguous analysis of massive rowing data, easy comparison of various samples (rowers in the boat, various stroke rates, previous and current data). It provides a feedback as a report or data replay combined with a video. Specific rowing video analysis is also included.
