Accessing GPS/GNSS Field Equipment and Support

The GETSI Field Project has purchased several teaching sets of five Emlid Reach RS2/2+ GPS/GNSS receivers (1 base, 4 rovers). These are available for loan to earth and allied sciences instructors in the United States (shipping costs only) from EarthScope Consortium, which runs NSF's Geodetic Facility and is the lead institution on the GETSI Project. GETSI and EarthScope can also provide consultation on field education planning and, to some extent, help to troubleshoot problems. Manuals to support the use of Emlid Reach RS2/2+ are below.

Requesting GPS/GNSS instrument loan

You can request the loan of several types of geophysics field instruments, including RTK-GPS/GNSS receivers, by completing the EarthScope Primary Instrument Center (EPIC) Experiment Schedule Requester.

Availability and timing — We currently have five 5-receiver teaching kits and could potentially purchase more if demand grows and funds are available. Kits are available on a first-come-first-served basis. Typical loans are 3-4 weeks but we will do our best to work with the scheduling that will best serve your teaching goals.

Cost — There is no rental fee for the equipment, but there is a shipping/receiving charge of $225 for a 5-receiver kit and $125 for a 2-receiver kit (an invoice will be sent to your institution). Previously, shipping was the responsibility of the borrowing institution, but we found that our organization had considerably lower rates than most universities. The shipping/receiving fee was initiated to ensure the rates were lower and predictable. Some short-course participants may have been informed that the shipping for their first loan will be waived. If these shipping costs are prohibitive for your institution (ie., community colleges or other lower-resource institutions), please contact to request a waiver. If your institution has lower shipping rates and you prefer to pay for shipping yourself, that is also fine.

Documentation for Emlid Reach GPS/GNSS receivers

Note: Emlid Reach RS2,RS2+, and RS3 have the same basic instructions. The primary difference is that RS2+ and RS3 can use 5G cellular for NTRIP corrections, whereas RS2 can only do 3G. Most geoscience users are not planning to use cellular corrections, so the difference does not matter. The RS3 has some additional capabilities, such as being able to take in corrections from a Trimble base station and having tilt compensation, but again, not critical to most geoscience educational use cases.

If your use case would benefit from NTRIP cellular corrections rather than a radio-based GPS/GNSS base station, you can refer to the NTRIP section of the Instructor Guide below and/or contact to discuss more about this with a staff member.
