|
---|
7 | =======
|
---|
8 |
|
---|
9 | Please prepare site logs in plain ASCII.
|
---|
10 |
|
---|
11 | Line length is limited to 80 characters.
|
---|
12 |
|
---|
13 | See http://igscb.jpl.nasa.gov/network/sitelog-submissions.html for
|
---|
14 | submission instructions, or email your log to igscb.jpl.nasa.gov if
|
---|
15 | you prefer. Site logs emailed manually are usually handled by
|
---|
16 | the CB within about one business day.
|
---|
17 |
|
---|
18 | Date and time formats are ISO 8061; see http://www.iso.ch/markete/8601.pdf
|
---|
19 | As a summary, CC=2 digit century
|
---|
20 | YY=2 digit year
|
---|
21 | MM=2 digit month
|
---|
22 | DD=2 digit day of month
|
---|
23 | T=date/time separator
|
---|
24 | hh=2 digit hour
|
---|
25 | mm=2 digit minutes of hour
|
---|
26 | Z=UTC indicator
|
---|
27 | /=separator when begin & end times are given
|
---|
28 |
|
---|
29 | Latitude/Longitude formats are aligned to ISO 6709:
|
---|
30 | Lat: +/-DDMMSS.SS
|
---|
31 | Long: +/-DDDMMSS.SS
|
---|
32 | A + or - sign is required. Leading zeroes must be used as appropriate
|
---|
33 | to maintain the DDMMSS and DDDMMSS format.
|
---|
34 |
|
---|
35 | "etc" indicates you may enter any relevant answer, not just a choice
|
---|
36 | ofthe suggestions shown.
|
---|
37 |
|
---|
38 | "F7.4," "A4" and so on indicate the FORTRAN-style format which the
|
---|
39 | response should have.
|
---|
40 | Example 12345.7 = F7.1
|
---|
41 | ABCD = A4
|
---|
42 |
|
---|
43 | Blocks which have a "N.x" definition (namely sections 3-10) should
|
---|
44 | always have the complete historic set of information; when a change is
|
---|
45 | made, the previous information is left (for example in section 3.1)
|
---|
46 | and the new information is placed in a new block numbered 3.2. Please
|
---|
47 | leave the .x sections uncompleted to remind yourself of the format
|
---|
48 | when the next change occurs.
|
---|
49 |
|
---|
50 | Please remove the response hints such as "(F7.4 N/S)" as you fill out
|
---|
51 | the log (except in the .x sections and Date Removed fields for
|
---|
52 | currently installed equipment, which you will leave). If an
|
---|
53 | answer in an optional field is unknown, try to learn the answer for
|
---|
54 | the next log update.
|
---|
55 |
|
---|
56 | If you have any questions not answered here, please feel free to
|
---|

|
---|
98 | --------------------------------------
|
---|
99 |
|
---|
100 | Receiver Type : (A20, from rcvr_ant.tab; see instructions)
|
---|
101 | Please find your receiver in
|
---|
102 | ftp://igscb.jpl.nasa.gov/pub/station/general/rcvr_ant.tab and use
|
---|
103 | the official name, taking care to get capital letters, hyphens,
|
---|
104 | etc. exactly correct. If you do not find a listing for your
|
---|
105 | receiver, please notify the IGS Central Bureau
|
---|
106 | (igscb@igscb.jpl.nasa.gov).
|
---|
107 |
|
---|
108 | Serial Number : (A20)
|
---|
109 | Keep the 5 significant characters of the serial number field in
|
---|
110 | SINEX in mind: do not enter "S/N 12345" instead of "12345" since
|
---|
111 | valuable information will be lost.
|
---|
112 |
|
---|
113 | Firmware Version : (A11)
|
---|
114 | Keep the 11 significant characters of the field in SINEX in mind.
|
---|
115 |
|
---|
116 | Elevation Cutoff Setting : (deg)
|
---|
117 | Please respond with the tracking cutoff as set in the receiver,
|
---|
118 | regardless of terrain or obstructions in the area.
|
---|
119 |
|
---|
120 | Temperature Stabiliz. : (none or tolerance in degrees C.)
|
---|
121 | This refers to the temperature of the room in which the receiver
|
---|
122 | is housed.
|
---|
123 |
|
---|
124 | Date Removed : (CCYY-MM-DDThh:mmZ)
|
---|
125 | In the block for the receiver currently in operation, leave this
|
---|
126 | line as is to remind yourselt of the format when the next receiver
|
---|
127 | change is made.
|
---|
128 |
|
---|
129 | 4. GNSS Antenna Information
|
---|
130 | ---------------------------------------
|
---|
131 |
|
---|
132 | Antenna Type : (A20 from rcvr_ant.tab; see instructions)
|
---|
133 | Please find your antenna in
|
---|
134 | ftp://igscb.jpl.nasa.gov/pub/station/general/rcvr_ant.tab and
|
---|
135 | use the official name, taking care to get capital letters, hyphens,
|
---|
136 | etc. exactly correct. If you do not find a listing for your
|
---|
137 | antenna, please notify the IGS Central Bureau
|
---|
138 | (igscb@igscb.jpl.nasa.gov). Please do not use antenna names from a
|
---|
139 | "Previously valid" section. Choose the corresponding new antenna
|
---|
140 | name. You may indicate a Radome code from rcvr_ant.tab in columns
|
---|
141 | 17-20 of the Antenna Type if desired.
|
---|
142 |
|
---|
143 | Serial Number : (A20)
|
---|
144 | Keep the 5 significant characters of the serial number field in
|
---|
145 | SINEX in mind: do not enter "S/N 12345" instead of "12345" since
|
---|
146 | valuable information will be lost.
|
---|
147 |
|
---|
148 | Antenna Reference Point : (BPA/BCR/XXX from "antenna.gra"; see instructions)
|
---|
149 | Locate your antenna in the file
|
---|
150 | ftp://igscb.jpl.nasa.gov/pub/station/general/antenna.gra
|
---|
151 | Indicate the three-letter abbreviation for the point which is
|
---|
152 | indicated equivalent to ARP for your antenna. Contact the Central
|
---|
153 | Bureau (igscb@igscb.jpl.nasa.gov) if your antenna does not appear.
|
---|
154 |
|
---|
155 | Marker->ARP Up Ecc. (m) : (F8.4)
|
---|
156 | This is the antenna height measured to an accuracy of 1mm
|
---|
157 | and defined as the vertical distance of the ARP from the marker
|
---|
158 | described in section 1.
|
---|
159 |
|
---|
160 | Alignment from True N : (deg; + is clockwise/east)
|
---|
161 | The positive direction is clockwise, so that due east
|
---|
162 | would be equivalent to a response of "+90"
|
---|
163 |
|
---|
164 | Antenna Radome Type : (A4 from rcvr_ant.tab; see instructions)
|
---|
165 | Place a Radome code from
|
---|
166 | ftp://igscb.jpl.nasa.gov/pub/station/general/rcvr_ant.tab here.
|
---|
167 | "NONE" indicates there is no radome.
|
---|
168 |
|
---|
169 | Date Removed : (CCYY-MM-DDThh:mmZ)
|
---|
170 | In the block for the antenna currently in operation, leave this
|
---|
171 | line as is to remind yourselt of the format when the next antenna
|
---|
172 | change is made.
|
---|
173 |
|
---|
174 | 8. Meterological Information
|
---|
175 | -------------------------------------------------------------
|
---|
176 | Height Diff to Ant : (m)
|
---|
177 | This is sensor height minus antenna height. In other words, positive
|
---|
178 | if the sensor is above the antenna. Please note that this convention
|
---|
179 | was used in the Notes.
|
---|
180 |
|
---|
181 | 12. Responsible Agency (if different from 9.)

---|
183 | The primary contacts listed here should always be the first choice for
|
---|
184 | questions about operation of the site. This person will receive
|
---|
185 | automated emails regarding site log or RINEX errors and should be
