New page

==GIBRALTAR - GPS-disciplined Frequency Standard==

Project leaders are Rick, W2GPS and Steve, N7HPR.

As currently planned, GIBRALTAR is a GPS-disciplined frequency standard board that will produce:

(1) a 10Mhz signal for the ATLAS bus

(2) a precision 1PPS signal for the ATLAS bus.

(3) a sampling signal for MERCURY

'''Current Status'''

Design elements have been discussed on the HPSDR list. This block diagram represents an intial proposal. Each block is based on existing proven circuiry, assembled in a new way to meet the needs of the HPSDR project. Comments are encouraged.

'''Design Narrative'''

GIBRALTAR recognizes two other designs, some elements of which may be included in GIBRALTAR:

- the TAPR REFLOCK II (http://www.tapr.org/kits_reflock_ii.html) designed by Steve, N7HPR (REFLOCK II is based on the work of Luis, CT1DMK, http://gref.cfn.ist.utl.pt/cupido/reflock.html)

- the commercial CNS Clock II designed by Rick, W2GPS (http://www.cnssys.com/cnsclock/CNSClockII.html)

'''GPS Receiver'''

GIBRALTAR may use one of two possible GPS receivers:

- the iLotus M12M (http://www.synergy-gps.com/images/stories/pdf/m12m%20timing%20prelim%20v11.pdf)

- the Trimble Resolution-T (http://www.trimble.com/tmg_resolutiont.shtml)

'''OXCO'''

The onboard OXCO may be one of two choices:

- Valpey Fisher VFT8HC18L5V-10.000 OXCO (http://www.valpeyfisher.com/PDFs/vft8s.pdf). This oscillator operates on 5VDC at 130ma during warm-up and 25ma steady state.

- Crystek CO27VH15DE-12-10.000 OXCO (http://www.crystek.com/ocxo/ocxo-description.htm). This oscillator operates on 15VDC at 300ma during warm-up and 110ma steady state.

Both of these oscillators cost over $250 each in small quantities.
