LAKE OSWEGO, Oregon USA — BigRedBee, LLC is pleased to announce two new enhancements to the popular BeeLine GPS Telemetry transmitter: the addition of Hardware Launch Detect and Digital Telemetry, further adding to the completely integrated, all-in-one package.

Hardware Launch Detect: An integrated acceleration switch (G-switch) is available to mark the beginning of flight data written to onboard memory. Coupled with the existing 'smart data logging' feature, the G-switch provides a more reliable method of detecting launch than the current software algorithm based on GPS altitude.

The BeeLine GPS transmitter packs an RF transmitter, GPS and RF antennas, GPS Module and battery all in one small package.

Digital Telemetry: The status of up to four digital inputs may be included in the data packet. Flight events such as airframe separation or motor ignition can be transmitted by connecting a simple break wire. Inputs from other digital systems may also be connected.

There are a total of four digital imputs available: 

• A and B are dedicated inputs, and are always available.
• C is shared with the hardware G-switch. If the G-switch is not used, then this is available as an input. If the G-switch is enabled, it may be possible to overlay another switch on this pin as long as it is "normally open".
• D is shared with the battery monitoring circuit. If the battery monitoring circuit is disabled, then D can be used as a digital input. This open must be specified at the time of your order, as it requires a hardware change on the board.

Prices for the BeeLine GPS Transmitter remain unchanged. The optional digital telemetry package is available for $40. This package includes an integrated G-switch, cables and two dedicated digital inputs.

Please see the BeeLine GPS documentation for more information regarding configuration of other inputs.
