We are designing a GPS chip for a light-show drone. We are using a Helical antenna with an RTK GPS. The GPS used is Ublox Zed F9P - RTK. We also have a 3-axis magnetometer on the chip. A 5V input voltage powers it. The MCU used is STM32. The chip size is 5x5 cm.
We are facing issues with the connections of the S2 Pad during the chip design in Proteus.
Kindly help us understand what would be the right way to complete this connection.
