Finished searching for components.

Below are proven component options to add RTK GNSS and a 900 MHz correction-link to your design. I’ve prioritized modules that are easy to integrate with your ESP32-S2 and have wide ecosystem support.

RTK GNSS modules (centimeter-level)

Table

Part	Notes	Flux link	Datasheet
ZED-F9P-00B	Dual-band RTK GNSS, industry standard, multiple UARTs, robust toolchain; external antenna via U.FL/connector on carrier	ZED-F9P-00B	Datasheet
NEO-F9P-15B	Compact u-blox multi-band RTK GNSS module; similar capability in smaller footprint	NEO-F9P-15B	N/A

900 MHz telemetry modules for RTK corrections

Table

Part	Notes	Flux link	Datasheet
XBP9X-DMUS-001	Digi XBee-PRO 900HP family; UART, U.FL; very mature AT/API stack; excellent for point-to-point RTK corrections	XBee-PRO 900HP	Datasheet
RFM95W-915S2	915 MHz LoRa module; robust long-range link; lower throughput but often sufficient for RTCM streams	RFM95W-915S2	Datasheet
WLR089U0-I/RM	Microchip LoRa module (863–928 MHz) with U.FL; LoRaWAN capable; can be used for P2P correction links	WLR089U0-I/RM	Datasheet
A110LR09C00GM	Proprietary 900 MHz FSK module with U.FL; simple UART/SPI integration; good range in 902–928 MHz ISM	A110LR09C00GM	Datasheet

Recommendations

Easiest path: ZED-F9P-00B + XBP9X-DMUS-001. Both are UART-friendly. XBee handles a continuous RTCM stream reliably at long range in 902–928 MHz ISM.
Low-power/robust link: ZED-F9P-00B + RFM95W-915S2. Throughput depends on LoRa settings; suitable for modest RTCM rates with proper spreading factor/bandwidth.
Compact RTK: NEO-F9P-15B when PCB space is tight.

Integration notes

Interfaces: Route one dedicated UART from ESP32-S2 to the RTK module (NMEA/UBX + RTCM), and a second UART (or SPI if chosen) to the 900 MHz radio.
Antennas: Use separate GNSS and 900 MHz antennas with good isolation and clear ground keepouts. Place GNSS as far from 900 MHz PA and LTE as practical.
Coexistence and decoupling: Keep RF modules on board edges, add solid ground stitching vias along RF boundaries, and follow each module’s layout guide. Add downstream ceramic decoupling near switching/noisy loads to reduce EMI coupling.
Regulatory: Confirm your region (e.g., 902–928 MHz) and set radio parameters accordingly.

A couple of quick questions to finalize the pick:

What region/band will you operate in (915 MHz ISM in NA, 868 MHz in EU, etc.)?
Do you prefer a UART-based radio link (XBee) or SPI-based (LoRa) for corrections?
Any hard constraints on PCB area or module height?

Once you choose the RTK + 900 MHz pair, I can add them to your schematic.
