 30 August 2023: IMPORTANT X90-OPUS Information

Sometime around Monday August 28, 2023, all X90D receivers stopped recording raw data.

We have determined that while the OEM GPS boards are tracking GPS satellites and have valid autonomous positions, they appear to have stopped outputting raw RT17 data streams. This issue is not related to a GPS rollover event (the last one was in 2019, the next one in 2038). These OEM boards have been end of life, end of service, end of support for a while. There is no updated OEM firmware for them.

The X90's have been out of production since 2016, end-of-sales late 2016 and the iGage warranty for the last device sold ended in 2018.

We know that the X90 OPUS is one of the most popular devices we have ever sold and judging from the number of calls we have gotten, we also understand that many that were still in daily use.

iGage is offering a trade-in program for X90's: $490 trade-in, with prepaid return shipping for X90's traded-in before the end of 2023. This offer is valid for the following new static and RTK receivers: iG5, iG8a, iG9, BRx7, Zenith 60. Only the X90 head will need to be returned, the batteries, chargers, cables cases need not be returned. (Only receivers sold through iGage distribution with new devices shipping to the USA are eligible. Devices marked as stolen in our database are ineligible for trade-in.)

The logical Static Only replacement for the X90 is the iG5 ($2030 with Trade-In). It uses the same download tool, has the same turn-on operation, has a standard USB Type C connector, is much smaller, runs for ~15-hours on the internal battery and has a Wi-Fi server for configuration and for use as a UAV NTRIP Server base. More information can be found here: https://iggps.com/iG5/iG5.htm.

If you have any questions at all, don't hesitate to call or write us: 801-412-0011 x0, support@igage.com.
