The dual-band GNSS platform combines L1 and L5 bands for resistance to multipath interference and meter-level positioning accuracy in urban areas. u-blox, a provider of positioning and wireless communication technologies, has announced the F10, its dual-band Global Navigation Satellite Systems (GNSS) platform. Interference from a cellular modem placed very close to a GNSS receiver can disrupt signal reception. Certain models of the module come with an RF circuit that allows both the GNSS and the cellular modem to operate without interference.
