Various arrangements are presented for using an estimated timing advance for user equipment communications. A location of an instance of user equipment may be determined. A first estimated distance between the user equipment and a communication satellite may be determined using the determined location of the user equipment and an estimated satellite location. A second estimated distance between the communication satellite and a communication network gateway may be determined. An estimated timing offset using the calculated first estimated distance and the determined second estimated distance may be determined. An uplink data frame may be transmitted by the user equipment to the satellite such that a timing of transmission of the uplink data frame is based on the calculated estimated timing offset.
