AValonRF, Inc., Will present and demonstrate itÂ?s Â?no moving partÂ?, Tracking Antenna receivers, Tuning Range - 460MHz-2.5GHz, C Band, KU Band, at the AUVSI chapter meeting in San Diego on February 24, 2005.

AValonRF, Inc., Will present and demonstrate it’s “no moving part”, Tracking Antenna receivers, Tuning Range - 460MHz-2.5GHz, C Band, KU Band, at the AUVSI chapter meeting in San Diego on February 24, 2005.

The TA04, TA08 and TA16 are a family of passive tracking antenna systems designed for video links to/from moving platforms that are tuned to any frequency band in the spectrum from 300MHz to 2.5GHz. Higher frequencies are available using external up/down converters. Tuning is via a RS232 port or via a remote control.

The AUVSI Lindenberg chapter meeting and luncheon will take place on Thursday, February 24, 2005, 11.30a.m. – 1.00p.m. , PS Business Park Conference room,

3954 Murphy Canyon road, suite D200, San Diego, CA.

Hoa Nghuen of the SSC Robotics Lab, San Diego, will present Unmanned Ground Vehicle (UGVs) work in progress at the Robotics System Works SSC SD, Code 2731, Robotics Systems Branch, http://www.spawar.navy.mil/robots/
RSVP to Ed Henning, ehennig@tamasco.com, Phone 858-496-0600

The TA system selects the antenna that has the best reception automatically and provides direction indication.

They include an array of 4,8 or16 (CP or LP) high gain antennas, cables, one, two or four DX04 series receivers and a DX002 or DX004 baseband diversity selector

Advantages of the Tracking Antennas:

· Extends the range of UAV/UGV/USV links 6:1 to 128:1 with (versus OMNI directional antennas) no moving parts and without increasing transmitter power.

· Works on vehicles and small boats in motion. No need to stop.

· Eliminates the need for direction finding.

· Small and low weight

. Tuning range - 460MHz-2.5GHz, C Band, KU Band

AvalonRF will also present and demonstrate its Wireless Digital Links for Unmanned Ground Vehicles – UGV, UAV, Micro UAV, USV and Robotics. The digital links are based on a unique modular concept where each link is composed from a combination of micro modules, connected together via a 100Mbaud full duplex daisy chained serial bus.

Approximate size and weight of each module: 60mm x 33mm x 9mm, 14 grams.

AValon RF digital module lineup includes:

TR430-3G - 1.53Mbaud/1W UHF/S band transceiver with GPS

TR430-3+G - 3.06Mbaud/1W UHF/S band transceiver with GPS


Module A - NTSC/PAL to MJPEG/MPEG1/MPEG2/MPEG4 Encoder based on the WISchip GO7007SB Encoder and Includes a smart video pre-processor DSP, RTC and VITC

Module B - Same as Module A with camera on board

Module C - Power PC with TCP/IP + USB 2.0 + IDE/ATA interface

Module D - MPEG4 to NTSC/PAL decoder (software dependent)

MPEG4 low latency CODEC or MPEG4 video conferencing controller.

Module E- - Various interfaces: MIL-STD-1553, Arinc 429, CAN and

OBDII, extender cards, mother boards (2,3,4,5 and 10 slots)

Module F - CPU, running Windows XP at 1.5GHz, 512MB DRAM, AGP - display controller with resolution of 800x600 to 1280x1024, 4GB HDD, 802.11g, 802.15 and GSM/GPRS for Wearable Computers

· Modules: General & Mechanical

Power - 5V-10V unregulated

Size - 60mm x 33mm x 9mm

Weight - approximately 14 grams

The digital links are divided into a payload systems and various ground systems;

· Payload systems

  • Includes a command & control receiver, GPS, MPEG4 video and a telemetry transmitter (Module A + TR430-3G or TR430-2G)

Size: 60mm x 33 mm x 20mm.

Approximate weight of the payload system: 28 grams

· Ground Systems (various options)

  • V38R Rugged PDA with TR430-2G, running Windows CE.
