Abstract
An exemplary method of calculating a position of a GNSS device (e.g., a GNSS rover device) comprises: at the GNSS device in an enhanced real-time kinematic (RTK) mode: receiving a first set of GNSS data corresponding to a first epoch; storing the first set of GNSS data in a buffer; receiving a second set of GNSS data corresponding to a second epoch that is after the first epoch; after receiving the second set of GNSS data, retrieving the first set of GNSS data from the buffer; and calculating the position of the GNSS device based on the retrieved first set of GNSS data and the second set of GNSS data.

A method of calculating a position of a Global Navigation Satellite Systems (GNSS) device, the method comprising:
- receiving a first set of GNSS data corresponding to a first epoch;
- receiving a second set of GNSS data corresponding to a second epoch that is after the first epoch;
- calculating, using an enhanced real-time kinematic (RTK) operation, a first estimated position of the GNSS device based on the first set of GNSS data and the second set of GNSS data;
- calculating, using an RTK operation, a second estimated position of the GNSS device based only on the second set of GNSS data;
- and
- displaying either the first estimated position or the second estimated position based on timing of the calculations.
A Global Navigation Satellite Systems (GNSS) device comprising:
- a display for displaying information to assist a user in positioning the GNSS device;
- a buffer;
- and
- processing circuitry to:
- receive a first set of GNSS data corresponding to a first epoch;
- receive a second set of GNSS data corresponding to a second epoch that is after the first epoch;
- calculate, using an enhanced real-time kinematic (RTK) operation, a first estimated position of the GNSS device based on the first set of GNSS data and the second set of GNSS data;
- calculate, using an RTK operation, a second estimated position of the GNSS device based only on the second set of GNSS data;
- and
- cause the display to display either the first estimated position or the second estimated position based on timing of the calculations.
