Artep, Incorporated, has produced space flight instruments for satellites, space shuttles, sounding rockets and research laboratories for over 25 years.
Artep specializes in supporting scientific projects ranging from
small experimenter groups to large-scale research institutions and the military.
Artep will design, fabricate, test, and integrate our custom hardware.
Artep provides complete support in all key project areas, including:
- Software Design
- Electrical Engineering
- Mechanical Engineering
- Materials Selection
- Optical Design
Artep, Incorporated, has developed custom electronics for interfacing research instruments to the WFF93 Telemetry Multiplexer hardware.
The most recent electronic boards were developed for two sounding rockets:
a Virginia Tech rocket that flew in February, 2011, from Poker Flat, Alaska, and a Naval Research Laboratory rocket scheduled to fly in April, 2012, from White Sands Missile Range, New Mexico.
The electronics card stack is housed in a robust, accessible mechanical design with conduction-cooled aluminum slices and an interlocking design for simple board replacement. Each slice houses a single card with up to 111 I/O pins available for interfacing to other boards, the payload or TM hardware.
