What Does It Do?
|
Simulated pass of Station
through Orion constellation. |
J-Pass uses state
vectors from NORAD and your latitude and longitude to create
regular reports of satellite viewing opportunities. The reports are
automatically e-mailed to you, and include information on each
satellite pass, such as rise and set times and locations, maximum
elevation, and brightness.
You can select up to 10 satellites plus the Shuttle, and choose
options for the report format and pass selection. We have a list of
over 100 satellites to choose from, and 55 cities to help you
specify your location. If your city or town is not in the list, you
can enter your latitude and longitude.
Each report gives 3 days worth of passes, and you can choose to
receive reports on Monday, Wednesday, and Friday, or just on
Fridays.
How Do I Subscribe
Use the form below. We will need a valid e-mail address and your
location.
Note: carefully input your e-mail address. If your report
"bounces" because it is undeliverable for more than two
weeks, the system removes your subscription. If you do not begin
receiving reports within a week, check back, you may have made a
mistake entering your address.
And no, we don't give out your e-mail address or use it in any
way except to send you these reports.
Selecting Options
When you enter your e-mail address to begin the subscription
process, you will then choose your location, time zone, report
formats, frequency, and satellites. You can return to our site at
any time and change your options. Note: our system doesn't know if
your area uses Daylight Savings Time, so you must manually make this
change every spring and fall.
