Emlid Reach RX2

01

RX2 has no SIM slot, no cellular modem and no radio, so it cannot fix a position on its own

Emlid calls RX2 a compact all-band network RTK rover, not a base-and-rover kit like the RS series. It carries no onboard cellular hardware of any kind. Emlid's own support page groups RX2 with the models whose serial number sits under the USB port cover. That is a different group from the Reach RS2, RS2+ and RS3, which do carry a SIM card slot. To turn raw satellite signals into a fixed, centimeter-level position, RX2 pairs over Bluetooth with a phone or tablet running the free Emlid Flow app. That phone supplies two things RX2 does not have on board: the internet connection, and, through it, the correction stream the fix depends on. RX2 is the rover half of a two-piece system, and the phone supplying internet and corrections is the other half, every time it runs.

03

Three ways to feed RX2 corrections, and every one needs internet reaching both ends

Emlid's own documentation names three correction sources, and all three run through the paired phone. First, any third-party NTRIP or CORS network, a subscription service you pay that provider for separately. Second, Emlid Corrections, Emlid's own built-in service, with one year included on a new receiver and a paid renewal after. Third, a second receiver relayed to RX2 over the internet. That is a Reach RS4 or RS4 Pro on Emlid's own named workflow, or another manufacturer's base station on its generic guide. Both base workflows require internet access for both receivers, not just the rover, Emlid states plainly. Once connected, RX2 is light on data, about 16 MB per device over 8 hours of NTRIP use. RX2 also needs a clear sky view, at least 30 degrees above the horizon in every direction, away from other electronics that can produce RF noise. Emlid says directly that a spot good enough for a smartphone's own GPS, indoors near a window, is not good enough for RX2.

05

Base-station mode and post-processing are not documented for RX2, and Emlid does not say either way

RX2's own documentation describes it only as a rover. No base-output setup exists anywhere in its documentation set, unlike Reach RS4 and RS4 Pro, which RX2's own documentation names as base units it can pair with. PPK, post-processed kinematic, means logging raw data and correcting it afterward rather than in real time, and Emlid states nothing either way about RX2 doing it. RX2's documentation covers RTK-mode work, including a guide for supplying ground control points to a drone's own PPK mapping workflow. There, RX2 works in RTK mode rather than post-processing its own logged data. One independent dealer states outright that RX2 cannot serve as a base station or do post-processing. Emlid neither confirms nor denies that for RX2, so we are leaving it open rather than guessing. Call if either capability decides your purchase, and we will confirm before you order.
