The GEO-CAPE ROIC In-Flight Performance Experiment (GRIFEX) is a 3U CubeSat developed by MXL that will perform engineering assessment of a JPL-developed all digital in-pixel high frame rate Read-Out Integrated Circuit (ROIC). Its high throughput capacity will enable the proposed Geostationary Coastal and Air Pollution Events (GEO-CAPE) mission concept to make hourly high spatial and spectral resolution measurements of rapidly changing atmospheric chemistry and pollution with the Panchromatic Fourier Transform Spectrometer (PanFTS) instrument in development. GRIFEX is the fifth satellite developed by the MXL research and student team. It is the third satellite development for JPL and NASA ESTO.
Operations Status Summary
(Note, more frequent updates will be given on MXL’s Facebook page.)
- 01 February 2015 09:00 EST — Operations are proceeding nominally and we are receiving data from HAMs around the world. Thanks for tracking! Power is positive, temperatures are safe, and GRIFEX is responding to commands. We are currently doing full system checks and working to upgrade publicly accessible operations pages. Here is spectral plot of our first transmissions. Note the frequency appears to be 2-3 KHz lower than expected. We estimate the center frequency to be 437.482 KHz.
- 31 January 2015 — GRIFEX launch was successful and the satellite is live an healthy. See below for current estimated position. Online telemetry viewing will be posted in the near future. Congrats to the other CubeSat teams and SMAP as well!
- Frequency: 437.482 MHz
- Output Power: <1W
- Modulation and Encoding: GMSK, AX.25 9600 bps,
- Beacon: 10 sec period, includes telemetry, format to be released soon
Data and telemetry from GRIFEX will be displayed in real time once launched. Check back post launch for details.
