RRC3+

Description

The Rocket Recovery Controller 3 (RRC3) is a barometric dual-

deploy altimeter,

with the features of high-end units, at the cost of those with a

more modest

feature set. In addition to basic dual-deploy capability, the

RRC3 is a multi-flight

recording unit, allowing you to fly all day, without the need to

stop and download

data in between flights. The RRC3 also provides a third, highly

flexible and

programmable “Auxiliary“ output which can provide staging,

airstarts, backup

events, and a host of other applications. The RRC3 can also

support real-time

data streaming capabilities in flight for telemetry or for

interface with other custom

control systems. Despite this unrivaled suite of intrinsic

capabilities and

expandability, the RRC3 still maintains its simple “buy it and

fly it” operations.

Specifications

Architectural Features

• 16MHz 16-bit MSP430 Series mCU
• 8Mbit SST Flash Memory
• MSI MS5607 Pressure sensor

Note: This high resolution altimeter sensor has a 24 bit ?S ADC,

with internal

factory calibrated coefficients which provide a precise digital

24 bit pressure and

temperature. The RRC3 design also provides a dedicated “baro-

only” regulated

power system and applies other noise reduction techniques to

further accurize

pressure data.

Operational Ranges

• Sport Unit: 40K MSL
• Xtreme Unit: 100K MSL

Note: For high reliabilty purposes, the “Xtreme” Altimeter

replaces the standard

RRC3 electrolytic brownout capacitor with a solid-dielectric

type for operations in

virtual vacuum and near space conditions. Electrolytic

capacitors have (semi-

)liquid dielectrics, which can boil off in vacuum.
