Global Activity Monitoring
and Economic Nowcasting

Macro monitor of global economies
with a specific focus on the impact of coronavirus

Activity Monitoring

SpaceKnow monitors tens of thousands of locations globally in near real time using a variety of space based sensors. The SpaceKnow advantage is our AI/ML based technology to analyze billions of observations to study changes at locations. Those ‘changes’ are multiple forms of activity that range from factory output to movement of product through supply chain points to construction or production at oil wells, ports, mines or any location that can be observed from space.

Thank you!

We will get in touch soon.

Location-Specific Knowledge

SpaceKnow’s location database has classifications of location-specific knowledge that allows clients to query activity at a ‘topic’ level (coal facilities, oil wells, etc). Clients can also provide locations of interest (ex. the points of a specific company or product supply chain) and SpaceKnow data can be accumulated at those locations.

Activity Measurement Indices

SpaceKnow’s Astronomics Product suite is about measuring change at locations. We offer a number of specific activity indices to measure activity:

Broad Activity Index
a normalized difference index of activity
Source = infrared sensors
Specific Activity Index
specific change algorithms run at each location
Source = radar
Nighttime Activity Index
luminosity of locations nightly
Source = optical imagery
Pollution Activity Index
proxy for industrial activity that measures NO2 and other environmental gases
Source = gas sensor satellite
Human Activity Index
small area human activity measured via cell phone movement data (city or smaller aoi)
Source = cell phone data

Thank you!

We will get in touch soon.

Combining monitoring factors - Model of Activity

SpaceKnow combines the different activity measures to create models to estimate economic or other activity benchmarks. We offer models that track and forecast the following:

  • GDP
  • Industrial Production and Purchasing Managers Surveys of Factory Output (PMIs)
  • Trade (Exports, Imports)
  • Electricity Consumption
  • Housing (starts and completions)
  • other topics that have publically available benchmarks


Models are designed to serve a specific purpose and can be bespoke designs to answer specific client questions.
