Topic 1 · Deep Space

Interplanetary Navigation 1

How you navigate when GPS doesn't reach: the Deep Space Network, radio ranging, Doppler tracking, Delta-DOR, optical navigation, the orbit determination loop, and the trend toward autonomous AI-driven deep-space nav.

Topic 2 · Earth / Geodesy

GNSS Technologies & Altimetry Cal/Val

GPS, Galileo, BeiDou & friends — trilateration, error budget, and augmentation (SBAS/RTK/PPP). Then how GNSS underwrites satellite altimeter calibration at mm-level sites like Corsica, Bass Strait, and Harvest.

Learning Outcomes

By the end of the session you will be able to:

OUTCOME 01

Explain why GPS does not work beyond Earth orbit and what radio-based alternatives replace it in deep space.

OUTCOME 02

Describe the Deep Space Network architecture and the three complementary data types: range, Doppler, Delta-DOR.

OUTCOME 03

Walk through the iterative orbit-determination loop and explain when optical navigation beats radio alone.

OUTCOME 04

Name the four major GNSS constellations and the main sources in the pseudorange error budget.

OUTCOME 05

Compare SBAS, RTK, and PPP augmentation strategies and their accuracy/latency trade-offs.

OUTCOME 06

Explain the role of dedicated cal/val sites in keeping satellite altimeter sea-surface-height retrievals at millimeter accuracy.
