Based on TLE data, using the SGP4 orbit model for space object orbit prediction, the position vector and velocity vector of the space object at future moments or the instantaneous root orbit information of the space object can be obtained. Time output uses UTC time format.

Billing Mode:

Annual package mode is a prepaid mode, where payment is made before usage, and settlement is based on the purchase cycle of the order. Therefore, before purchasing, you must ensure that the account balance is sufficient.

Pay-as-you-go mode is an instant consumption mode, where the interface is called in real-time and the account balance is consumed in real-time, at a rate of 0.005 yuan per call. When the account balance is insufficient, the interface call will fail. Please ensure that the account balance is sufficient.

Renewal:

Annual package service will affect the normal invocation of the algorithm after expiration. If you wish to continue using the orbit prediction algorithm, please renew as soon as possible. Renewal includes two methods: manual renewal and automatic renewal. You can choose based on your needs. To learn more about renewal requirements, please refer to Renewal Overview
