+# MegaMetrum
+
+This is a high-end recording dual-deploy altimeter for high power model 
+rocketry with integrated GPS and telemetry link.  The features included
+make MegaMetrum the ideal choice for complex projects including sustainers
+on multi-stage projects.
+
+For the latest MegaMetrum firmware and related ground station software, please
+visit the [AltOS](../AltOS) page on this site.
+
+These are no photos of MegaMetrum to share yet.

+## Artifacts ##
+
+There is a single manual for MegaMetrum and most other Altus Metrum products,
+which is available in [html](../AltOS/doc/altusmetrum.html) and 
+[pdf](../AltOS/doc/altusmetrum.pdf) formats.
+
+The hardware design current gEDA files are available from 
+[git.gag.com](http://git.gag.com) in the project 
+[hw/megametrum](http://git.gag.com/?p=hw/megametrum;a=summary).  
+
+## Future Plans ##
+
+MegaMetrum v0.1 prototypes are working and flight testing is underway.
+
+There will be at least one more prototype version to try out a different
+GPS receiver and improve various design details... most likely at least
+2 more prototype versions before we go to production.
+
+No firm schedule for production and sale of MegaMetrum has been set yet, 
+but we hope to offer this product in time for the 2013 flying season.
