Announcing the UAV MegaCam
Now Available!
MegaCam is a multi-megapixel imaging payload for UAVs, optimized for low bandwidth datalinks.
This system enables realtime extremely high resolution image transmission over typical UAV datalinks.
Existing UAV datalinks can be taken full advantage of to send back high resolution images.
Realtime Transmission
High quality 4 megapixel
images can be transmitted in 15 to 30 seconds over a typical UAV
datalink (complete cycle time including image compression and decompression is higher but
typically 40 seconds to a minute for 4 megapixels, down to about 3 to 5 seconds for smaller images).
The system supports realtime image transmission as well as onboard archiving.
It works, it works great, and it's here now.
New image compression technology smashes the idea that you need megabit datalinks to send multi-megapixel images.
The system works well over typical 38.2 kilobaud payload datalinks UAV
avionics provide (but can operate at bandwidths from 2400 baud to 115.2
kbaud).
Image quality and transmission time can be traded off for optimal performance.
Developers can integrate the imaging system with their own datalink, or
users can drop in a ready to go independent imaging system.
**The system can also send multi megapixel images over ultra low
bandwidth satellite links such as Iridium. This pushes
multi-megapixel image transmission times into the several minute range,
but it's a stunning, practical capability that did not exist before.**
Piccolo Ready
This system is compatible with the Cloud Cap Technology Piccolo avionics, and allows megapixel images to be transmitted over the Piccolo's standard datalink.
The system can also be operated standalone with a transparent datalink, and supports Iridium satcomm.

Sample Images
Click on the following
thumbnails for samples of 4 megapixel images capable of being transmitted in 20
seconds over a 38.2 kbaud link (complete cycle time is longer).
Note that these are large downloads to preserve the transmitted quality
of the image. The filesize of these sample photos does not
reflect the compressed filesize as transmitted by this system.
These photos provide an indication of the level of detail (in a complex
image) that is preserved at this quality setting which is optimized to
UHF transmission. Higher quality or faster transmission times
are possible.
