Ready for Any Mission Critical Road Trip

When I told a neighbor about LocusUSA’s DiagnostX over-the-air radio analyzer, he immediately replied, “Oh kind of like my OnStar™ system in my truck?! It tells me when it needs maintenance. It’s all diagnostics!” I had to agree with him but had no idea how extensive OnStar’s diagnostics system really was at the time. I gleaned from its website that OnStar Vehicle Diagnostics automatically performs monthly checks on a vehicle’s operating systems such as its transmission, stability control, airbags, emissions, brakes, and tires. Then, it emails the owner a simple report and shares important information with the local dealer in order to set up a maintenance service appointment. The convenience of this type of diagnostics is that it is performed over-the-air, is autonomous and nonintrusive to the system, and occurs without user intervention. Drivers can have a good feeling that their vehicle is operating as it should. This is an excellent example of proactive maintenance instead of reactive maintenance when something wears out or breaks down before fixing it.

How is LocusUSA’s DiagnostX similar to the proactive maintenance approach of OnStar’s Vehicle Diagnostics system?

DiagnostX automatically performs checks on a radio’s alignment by capturing all its control channel transmissions while in use in the field.  It takes measurements and stores the calculated results in a database for later retrieval to determine radio conformance. The analyzer checks for frequency error, low and high-level deviation, modulation fidelity and average symbol deviation. It also reports BER, RSSI and SNR for each transmission received. These measurements are compared to established thresholds to identify any indication of a poorly operating radio. The DiagnostX viewer allows the radio technician to review the captured metrics and schedule a radio to come in for service. DiagnostX offers the same convenience as OnStar because it is constantly monitoring and evaluating the radios operating on a system over-the-air, autonomously, nonintrusively, and without user intervention. Radio users and technicians can have a sense of security knowing their systems are operationally ready for any mission-critical road trip.
