N2 - In this paper, an integration methodology for Carrier phase Differential Global Navigation Satellite System (CDGNSS) attitude determination and relative positioning is presented. The integer ambiguity resolution performance is evaluated using data from ground and flight tests. Performance is evaluated in terms of Time-To-First-fiX (TTFX). The results show that the integrated system can significantly improve the integer ambiguity resolution performance by decreasing the TTFX. It is shown that the improvement can be from a few seconds to a few minutes. The performance is enhanced when multiple baselines from the attitude determination system are used.
