HEOL DESIGN is the first company to produce Trimble GPS receiver clone boards, which are based on the Copernicus II and RES-SMT-360 high performance GPS chipsets. These OEM board are designed for use in embedded and industrial applications requiring high accuracy positioning and timing information.
They can also be used as a replacement and upgrade for users of the Trimble
 Lassen iQ / SQ (PN 46240-00, 46240-05, 46240-10, 46240-20, 46240-25, 54854-00)

All our clone boards have exactly the same procotol as the original Trimble boards (TSIP, NMEA, TAIP)

Also, the N024, N016 and N021 ( ACE, iQ and Lassen SKII clones) integrate a processor, for matching with parity ODD, and additional software features (including future Rollovers management).
