This thesis proposes and implements a new and novel solution on simulators and real devices to solve the mobility problem in a VPN. The new solution adds mobility support to existing L2TP/IPsec (Layer 2 Tunneling Protocol/IP Security) tunnels. The new solution tunnels Layer 2 packets between VPN clients and a VPN server without using Mobile IP, without incurring tunnel-re-establishment at handoff, without losing packets during handoff, achieves better security than current mobility solutions for VPN, and supports fast handoff in IPv4 networks.

This thesis presents the design of a test asset system capable of testing GNSS receivers for speed accuracy and the Uncertainty of Measurements (UOM) analysis for this system. The test asset system utilises a variety of engineering solutions and is capable of maintaining high accuracy benchmarks in speed measurements. The test asset system has an UOM equal 0.4 km/h for the entire range of speeds used for GNSS speed testing. The system was designed, assembled and tested to ensure the system maintains its integrity and capability to test GNSS receivers for speed measurement.
