April 7, 2019 GPS Week Number Roll Over problems?
If your Meade GPS thinks it's 2099, fix it for free with StarPatch!

Imagine if your telescope could access the Global Positioning System so that it always knew when and where you were observing from. No more checking your watch, looking up site coordinates or fiddling with the keypad to enter the date, time, latitude and longitude. StarGPS uses a single cable to connect your telescope to the GPS receiver and automatically input these values... making your telescope setup much easier and more precise!

for Vixen StarBook

If you own an Autostar 497/497EP or Audiostar controlled telescope such as the Meade ETX, LXD, LX90, LX80, LT, LX65 or LX85 series or an upgraded LX200 Classic then we recommend that you consider upgrading to the StarGPS Package which adds a StarPatch registration key ($79) and USB-ASTAR cable ($30). StarPatch uses your Windows PC to perform a one-time, quick and easy installation that reprograms the handset to accept raw GPS data. You can then connect the GPS to your telescope, turn the scope on, and watch as the handset displays incoming GPS data including time, number of satellites and signal strength as shown below. Once a location fix is obtained the handset will beep, display the results and skip ahead to the "Align:" prompt. Click her for more information about StarPatch.


The StarGPS Package includes:

  1. High performance GPS-NX02 receiver
  2. GPS-ASTAR cable to connect the GPS to the handset. If you have an LX65/85 you may require a GPS-ASTARX cable (contact us if you are not sure which cable to select).
  3. StarPatch software registration key to add GPS Setup capability to one Autostar 497/497EP or Audiostar handset
  4. USB-ASTAR cable to connect your PC to the handset
