Collecting Static Data OPUS-Static, OPUS-RS and OPUS-Projects Additional information on OPUS-Static and OPUS-Rapid Static can be found in the ‘OPUS’ section of this manual. Prior to using the receiver, charge the battery to ensure that the static occupation is not interrupted by power failure. A fresh battery when new and fully charged will run the receiver for about 5 hours.

Turn on the receiver. After 30 to 90-seconds, you will see the Yellow “Files” LED flash once every epoch (default 5-seconds) as the receiver records observables. Check that 5 or more satellites are tracked (the blue LED will blink 5 or more times.) Wait an appropriate time period for data collection: OPUS-RS (Rapid Static)
Downloading Data from iG3s Reciever Summary: Turn on the GPS, wait fo 10-seconds; plug in the USB Cable to your computer. The iG3s receiver mounts just like a USB thumb drive (flash drive) on your Windows computer. No special drivers are required.
The drivers are built into Windows XP, Windows Vista, Windows 7, Windows 8 and Windows 10. If your iG3s receiver does not mount or an error message is displayed, you can usually unplug the receiver, wait a moment, then plug it back in.
Using the Download Tool Assuming the iG3s receiver is plugged in and has mounted (as a lettered drive), just press: The program will automatically switch to the '_New' project and download every new file from your receiver. As the .HCN binary files are downloaded from the receiver they are automatically converted to RINEX and added to the '_New' project and finally displayed in the occupation grid.

OPUS: What is it? OPUS (Online Positioning User Service) is a free service provided by the NGS (National Geodetic Survey.) From the NGS Website: “This Online Positioning User Service (OPUS) provides simplified access to high-accuracy National Spatial Reference System (NSRS) coordinates. Upload a GPS data file collected with a survey-grade receiver and obtain an NSRS position via email.
OPUS-RS (Rapid Static) Standard OPUS-Static sessions require 2-hour observations. OPUS-RS sessions can be as short as 15-minutes. However, OPUS-RS solutions are not available universally. In general, OPUS-RS requires: 3 (or more) CORS within 250 km of your site your site must be within 50 km of the polygon formed by the CORS sites If you are working in Southwest Nevada, along the high line of Montana or in North or South Dakota, OPUS-RS probably...
In some areas there is a risk that if a single CORS site is unavailable, your OPUS-RS job will not be processed. Caution and planning are suggested for OPUS-RS jobs. OPUS-Projects OPUS Projects is a relatively new online tool. Its use requires taking a NGS training class, but the invested time is well worth it as OPUS-Projects will allow you to combine the observation files from multiple receivers and multiple...
OPUS is sometimes unavailable or takes longer than other times.

down a few seconds before the battery expires. However, if the battery has been allowed to deplete and then is used when downloading to the computer the battery will likely run down while the files are transferring. Downloading files keeps files open most of the time and the probability of a nearly depleted battery failing during transfer is quite high.
