40 plus years experience in Electronics and Systems design
GNSS RTK Systems.
Analogue, Digital, Microprocessor hardware and firmware design
Real Time Kinetic RTK dual frequency L1,L2 multi constellation GNSS receivers made affordable for agriculture and other lower cost areas.
No subscription charges, moderate to low cost, typically cm accuracy depending on baseline.
Solar PV proportional heating Controller
Designed and manufactured in UK saves on hot water heating costs. Utilises spare available export power to heat hot water. Accuracy <100 watts. Excess export power in excess of this gets proportionally fed to a resistive load.
Simple, accurate, High mean time between failure MTBF typically 40 years
