Ashtech Z12 GPS Receiver & Z Reference & Ranger © Brooke Clarke 2009 - 2017 Z12 Photos P The top is held on by three screws on the left panel and three on the right panel. The GMT shown: 21:49:14 is correct. SVs 25, 26, 30, 23, 13 & 16 are carrier locked but not phase locked. Data Port 12mm ID Fischer Connectors Some Z12R receivers have DB-9 connectors and some have Fischer Push-Pull connectors. These are NOT 7 pin Fischer connectors like on the small box Z12. 12 VDC Input 9 mm ID Fischer 3 pin Connector Background. Ashtech Locus Static GPS Surveying receivers. Or Best Offer. Free Shipping.

Ashtech developed a better way to use the encrypted L2 signal. The prior art was to square L2 and the Ashtech method has a better signal to noise ratio making it superior. Antenna Drive Voltage The output voltage is 9.7 VDC positive on the center conductor of the Type-N male connector. Mixpad code free. This will smoke a 5 Volt antenna like my roof top unit. Some options: • Find an antenna rated for L1 and L2 that accepts 10 Volts. This is the desirable solution if it's a geodetic grade (ground plane or choke ring) antenna. • Use an L1 & L2 antenna with 5 Volt drive through a splitter that provides the drive and a DC blocked port to this receiver. - carries splitters (and they are on eBay) - carries splitters (and they are on eBay) • Make an adapter that takes in the +10 volts, regulates it to +5 and bypass the RF from in to out. Hold down the ^ (up arrow) while powering up. Enter YES (the number 8 key) when asked if this is what you want to do. It now ends up searching for SVs. Setting External Ref Freq When the EXT FREQ is set to 0.0 the internal frequency standard is used, i.e. It's not a requirement to use an external standard. Press 4, then e, then use arrow keys to highlight EXT FREQ, press e, set to 10 MHz, then press 3, Wait for screen to change to Locked, then press e. If the external reference GPSDO is not locked then the Z12 does not acquire satellites. Something happened to the when there was a power glitch. L1/L2 Antenna. AeroAntenna Technology with the Choke Ring comprises the which has known phase centers for L1 and L2. ![]() Antenna is L1 and L2 runs from 5 to 18 VDC. Find mating connectors. Record receiver data and convert to RINEX format. Submit RINEX file to - which uses three CORS sites to reduce data. -------------------- ()- 39°56′11″N 120°56′53″W Enter the co-ordinates into the text boxes to try out the calculations. A variety of formats are accepted, principally: • deg-min-sec suffixed with N/S/E/W (e.g. 40°44′55″N, 73 59 11W), or • signed decimal degrees without compass direction, where negative indicates west/south (e.g. 40.7486, -73.9864): Point 1:, Point 2:, Distance: 207.3 km Initial bearing: 247°06′23″ Final bearing: 245°41′41″ Midpoint: 39°34′06″N, 122°03′43″W And you can (aren’t those Google guys wonderful!) Z Reference This GPS receiver includes an input for an external frequency reference, unlike the Z12 above. This might better lend it to precision GPS work. Photos ZR Fig 1 ZR Fig 2 ZR Fig 3 ZR Fig 4 Inside Compact Flash drive: SanDisk 90 MB Battery: TL-5/86 3.6V (unknown condition) Disassembly Remove front panel (+) screws and hinge down the panel. NOTE: Be very gentle pulling off the connectors after noting which goes where (mine were marked I, II,X and O, but the X socket came off the PCB and needs to be soldered back down. O: switch X: circle light II: Satellite light I: Drive light Remove the three hex head screws using a 3/32' ball end hex wrench. Remove the back panel (+) screws and slide the PCB and rear panel assembly out the back. Operation Ranger This GPS receiver has the look and feel of the rack mount Z12, but much smaller. If you compare this receiver to the one at the top of the page, it's the same size as the main part and has an identical front panel. But the rear panel uses different connectors than the above receiver and different from the field version Z12 shown in the Z12.pdf manual. 8 Feb 2017 - added Photos Fig 1 Carry Bag Fig 2 Front panel with Z12 look and feel Fig 3 Field connectors different than rack unit. Power In dust cap: Amphenol 97-60-10 Power Cable connector: 3106A10SL-3S Power Voltage: TBD Power Connectors To make power cable use: 3106A10SL-3S. The two power connectors both have pin-B as chassis ground, but pins A and C are not interconnected on them. This implies that the idea is to have two independent power sources so that one can be changed while the other provides continuous power. For that to work there needs to be diode isolation so the dead battery does not drain the good battery. The ZY-12 supplemental manual has the pin out table. Pin Function A +10 to 32 VDC B Chassis Gnd C -10 to 32 VDC Guess input as 9 to 32 VDC. Download Xtools Pro Arcgis 10.2 Crack >> Download Xtools Pro Arcgis. Xtools pro free download.
