Main difference between the Standard L1+L2 Double Frequency RTK sets and the Hybrid RTK sets.

Hybrid GNSS System use a Double Frequency L1+L2 Base (RTK Transmitting only) and an RTK L1-Only Rover that can achieve a Performance of accuracy similar to a standard Double Frequency System at a very low price, but without the negative stability problems that a L1+Only RTK system presents. Take in consideration that a Hybrid System has less Base-Line range than a Double Frequency RTK. More information here: https://gnssrtk.com/

 NORTH SmaRTK Double Frequency and Hybrid Frequency Receivers (Single Frequency Rover and Double Frequency Base) comparison.

Notes:
(+): A Hybrid-Frequency set is formed by a Transmitting-only L1+L2 Base and a full L1-Only Rover. The main technical difference between the L1-Only Rovers and the L1+L2
Receivers is the Cold-Start time to get Fixed position. For L1+L2 Receivers is just a few seconds and for L1-Only the time is normally between 2-5minutes.
The L1-Only receiver is more apt for open areas where multipath and obstacles are not an issue, and for low budget markets.
(++): The "LIGHT" versions are complete Receiver sets but without Carrying Case, to be used for OEM or UAV applications
A*: This number indicates how many SmaRTK receivers are in the set. The accessories are complete for each application, except tripods and poles.
B*: The exclusive Auto-Caster function allows direct Base to Rover link by Mobile Network, so UHF radio is not always required. Can be set as a temporary or permanent CORS station.
C*: Base receivers that are sold without internal UHF radio support, can be upgraded at any time with UHF board installation.
D*: This sets does not include internal UHF on the base because an external Harxon 35W Radio is included.
E*: The included PDA is the Valkir 9 with Windows 10 PC and 8-inch touchscreen
F*: This software is the North GIS Surveyor, a very basic software to Collect, Stake out, Collect auto points and 3D surfaces, in case the Carlson is not required for some reason.
